The Need for maintenance?

Transformers are a costly and necessary portion of any machinery. As it is used to minimize power line issues such as electrical noise, spikes, surges, and ground loops, insulation transformers are used. It also offers high resistance to insulation and complete electromagnetic and electrostatic shielding. So, it is best to conduct annual maintenance check ups on your machinery to get maximum efficiency and increase product life.
Nantech Power Systems Pvt. Ltd. which gives the best hardware solution in Chennai city also delivers AMCs (Annual Maintenance Contract) when selling our electrical goods.

Annual Isolation Transformer Maintenance Checklist

• It is important to inspect the air fans, oil pumps, among other things used to cool down a transformer and control circuit annually
• Make sure you use only soft cotton cloth every year to clean all the bushings of your electrical transformer.
• OLTC's oil status should be closely investigated on an annual basis.
• Make sure the interior of all the marshaling boxes is washed out annually. Check the proper functioning of the heaters for room and light. All the control and relay wiring terminal links need to be strengthened at least once a year.
• It is important to clean all control switches, alarms and relays along with their circuits, the Remote Tap Changer Control Panel, and the Relay and Control Panel with an acceptable cleaning agent.
• If they have the requisite oil level, check all the pockets for the Winding Temperature Indicator and Oil Temperature Indicator and make sure to top it up if needed.
• It is important to verify the proper functioning of the Buchholz and Press Release System relays on an annual basis.
• Ensure that the resistive force of the earth connection is determined and that the rizer must be measured with a clamp on the earth resistance meter. This has to be done on an annual basis.
• Replacement of capacitors:

1. Capacitance value changes can result in variations in the output voltage of the CVT-
   It’s expected usual manufacturing tolerances in the value of a spare capacitor to adjust the nominal setting of the original output voltage by less than 1 percent. With CVTs using a spare capacitor of the same color dot, the estimated output voltage difference will be less than 0.3 percent
2. Over extended periods of time, the physical dimensions of commercial capacitors shift-
   Condensers would be comparable in size or smaller in general terms. A factory repair for units up to 3 kVA is recommended in case of any anticipated problem. When handling high voltage capacitor installations, caution must be taken

Replacement and warranty periods might be necessary factors to consider while purchasing electrical appliances. But, the AMC (Annual Maintenance Contract) should also be taken into consideration before making your decision. To put it simply, it’s an agreement between you, the consumer, and the product’s company that ensures that you get repairs, and maintenance for free or nominal fees during the contract period, from the authorized executives of the company. We at Nantech provide AMCs while selling our electrical products and here’s a list of how you can benefit from it:

1. Less Expenditure Cause It’s Economical

AMCs make sure that the repairs and services don’t get too pricey! Additionally, you know the upfront prices if any, ensuring that you aren’t falsely tricked into paying more than what is officially needed.

2. Emergency Power Failures? Get Help Instantly!

Unforeseen emergency situations can occur at times and leave you puzzled. But in case they occur during the contract period, you can instantly get help from the company! Just call the customer care of the product company and help will arrive at your doorstep.

3. Authorised Personnel At Your Disposal

The tech support executives working at the product’s company are extremely resourceful people since they are well-trained for their jobs. Of course, in case of emergencies, you can call a repair person from your local hardware store but chances are that they might be relatively unskilled and you might be overcharged for the maintenance or repair task. Or even worse, you can be scammed! Fortunately, authorized personnel are at your disposal, whenever needed and will do the job as per the official price.

4. Efficiency

Electrical devices may become less efficient with the passage of time. However, maintaining them verifies that the devices are performing as per their given specifications. Lower efficiency can even lead to more expenditure. And hence, services are necessary so that you don’t end up spending more due to an inefficient device!

Should you renew your contract after its expiration?

It’s often a debatable topic for some folks who state that maintenance isn’t necessary as long as the device is working perfectly. But contract periods offer you security, safety, and peace of mind during emergency situations. Moreover, you can’t get to know the efficiency and persisting potential problems within a device, without carrying out routine maintenance checks. These checks can even avoid or tackle a problem before it actually happens and make things go haywire.

In conclusion, Annual Maintenance Contracts are necessary to fortify your product and reassure you in times of crisis. We at Nantech sell a wide range of products with these contracts, to make sure you get help when you need it the most!

This city is already advanced in technologies providing the futuristic level of hardware designs. If you are looking for servo voltage stabilizers your search ends here.

INTRODUCTION: -

Voltage stabilizers are used to stabilize or regulate the voltage if the voltage is fluctuating over a given range. The main purpose of stabilizers is to provide a constant voltage to load or appliances.Servo Stabilizer is a Servo motor driven stabilization system that performs optimum voltage supply.

Servo stabilizer is an electromechanical device therefore its voltage correction speed is slower than static voltage stabilizer.

Following are the two types of servo voltage stabilizers

• Air-cooled Servo Voltage Stabilizers
• Oil-cooled Servo Voltage Stabilizers

Air-cooled Servo Voltage Stabilizers:

Air-cooled Servo Voltage Stabilizers are very much useful for various electrical as well as electronic applications.The servo stabilization mechanism with air-cooling means efficiently ensures optimumvoltages.This stabilizer includes a transformer and a power control circuit for controlling output AC voltage. The negative feedback circuit controls the voltage or power automatically and regulates it to a level that’s set or required. The most effective part is that within the entire operation, the voltage regulator doesn’t require any manual interruption, it functions automatically.

Oil-cooled Servo Voltage Stabilizers: -

Oil-cooled have inherently higher short-time or sustained overload capacity as compared to Air-cooled types. The main difference between oil-cooled and air-cooled stabilizers is the capacity of oil-cooled stabilizers are for higher capacity. These are used in places where there is a high frequency of fluctuating voltage in the power supply. Anoil-cooled stabilizer guarantees that the fluctuation in the power supply does not affect the electronic or electricaltypes of equipment.

Chennai city is leading in the hardware industry. From the past few years, it has advanced alot in hardware technology development. Foremost Nantech Power Systems Pvt Ltd., one of the most important major hardware manufacturing companies that provide top-level transformers.

Constant voltage transformer: -

Constant Voltage Transformer (CVT)is a non-linear transformer also known as Ferro resonant Transformer (Ferro).

Ferro resonance is a regulated voltage output provided by CVT through an electromagnetic phenomenon.

CVTs are basically 1:1 transformer that is excited high on their saturation curves, thereby providing an output voltage which isn’t significantly tormented by input voltage variations. This special characteristic is that the foundation of the appliance of Ferro resonant transformers as power conditioners.

Ultra-Isolation Transformer: -

An Ultra isolation transformer is a transformer that’s accustomed transfer electricpower from a source of alternating current (AC) power to some equipment or device while completely isolating the connected device from the power source, usually for safety.

An isolation transformer is a transformer, usually with symmetrical windings, which is used to decouple two circuits. An isolation transformer allows an alternating current(AC) signal or powers to be taken from one device and lead into another without electrically connecting the two circuits. Isolation transformers block the transmission of direct current (DC) signals from one circuit to another, but allow AC signals to pass through. They also block interference caused by ground loops. Isolation transformers with electrostatic shields are used for power supplies for sensitive equipment like computers, Lab Instruments, CNC Machines, Medical Equipments, etc.

Isolation Transformer employs a novel multiple shielding technique that reduces the inter-winding capacitance to a large extent and increases the DC isolation.

(1kVA is 1000 VA)

What are tubular batteries?
Tubular batteries are also known as deep discharge batteries is a lead-acid battery. They provide a small amount of current, for example, 5 Amperes, for a long period of time. The electrodes of these batteries are thicker than the regular ones and hence cannot release a large amount of current. Moreover, they cannot be used in domains where a large amount of current is required in a relatively short period of time. Although they don’t provide high current, they last for a longer duration as compared to regular flat plate batteries.

WHAT ARE THE DIFFERENT TYPES OF TUBULAR BATTERIES?

Nantech Power Systems provide a multitude of tubular batteries:

• Exide
• SF Sonic
• Luminous
• Rocket
• Okaya

As there are several options, we have provided a brief yet comprehensive comparison of different tubular batteries that you can choose from.

Conclusion

To conclude, when you decide to purchase a tubular battery, make sure you understand your needs perfectly and are aware of the environment you are residing in. For places that have hot and humid weather conditions, like Chennai, all of the above Nantech Tubular batteries work perfectly well.

Power cuts and load shedding can be quite troubling. And getting an inverter-battery setup helps a lot. But choosing an inverter battery might be a daunting task for most of us, especially if you are getting it for the first time. Don’t worry, we at Nantech decided to put this comprehensive guide and here’s everything you need to know before getting one:

How Long Do You Need A Power Backup?

Knowing how long you need the power backup to last, helps you choose the battery with the right capacity. Let’s say you face power cuts for 2 hours everyday and you need a 12V battery as a power backup for the entire time. And you want to run the following appliances:

Required Capacity of Battery = (Hours of Power Backup) * (Power Required in Watts) / (Voltage of Battery)

Required Capacity of Battery = 2 * 270 / 12 = 45 Ah

Most batteries in the market are around 135-150 Ah and if the above case is equivalent to your real requirement, then you can even go for cheaper and lower capacity batteries!

Cost
It is essential to calculate and decide the budget as per your requirements, since the inverter and battery dealers may persuade you to buy more expensive batteries. The above example will help you with the necessary calculations and prevent unnecessary expenses.

Battery Type
Lead Acid Battery:
These are of two types:

• Flat plate battery: recommended for areas with frequent power cuts, lasting short durations.
• Tubular battery: it’s bigger than flat plate battery and is recommended for areas with power cuts lasting long durations but fewer in frequency.

Gel Battery:

• Recommended for offices and homes where power backup lasting several hours is necessary.
• Zero reduction in performance, even after years of usage.
• No water top-up and maintenance required.
• Easy installation.
• Eco-friendly battery with minimal toxic emissions.
• No chance of acid spillage!

Weight of the Battery

The weight of the battery is something you might overlook and not take into consideration first but it tends to be an important factor for those who are frequently on the move! Batteries have different weights when they are filled and empty(dry). If you frequently shift places, consider buying a less bulky battery. In case you still need a heavy battery, look for the ones equipped with a trolley.

Replacement, Warranty and Services

Most reputed companies offer free services within the warranty period (also called ‘flat warranty period’). In case your battery faces issues within a few months of purchase, it could be replaced, provided the fault occurs and is registered within the replacement/pro-rata warranty period. It also helps if the company provides installation and maintenance services, since this can be a tough task for most individuals. Hence, warranty period is also an important factor while purchasing a battery!

We hope this comprehensive guide helped you and made the task of buying a battery easier! If you are looking for an authorised battery dealer, we at Nantech sell batteries of numerous reputed companies.
