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

Preventive maintenance can help to detect problems and provides:

• Increasing transformer life through condition monitoring
• Lessen Maintenance Costs
• Safe and reliable operation
• Avoid a sudden breakdown

Conclusion: A famous saying “a stitch in time saves nine” used to express that it is better to spend little time and effort right now to avoid major problems in the future which may lead to cost more money sometimes life too.

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!
