Frequently Asked Questions

1. How often should transformers be inspected and serviced?

The amount of use and the surroundings where the transformer is stored, determines how frequently it needs maintenance. The best environment for a transformer is one that is dry and clean; in this setting, the unit just needs annual inspections and maintenance. However, transformers kept under environmental conditions where the air is contaminated by substances like chemical fumes or dust, will need more frequent (every 3-6 months) inspections.

 2. What is the difference between a power transformer and an instrument transformer?

A power transformer is primarily used in power transmission and distribution to either step up or step down a voltage level. While an instrument transformer is used in a circuit for the measurement of voltage or current.

 3. What is meant by impedance in transformers?

Impedance is the transformer's ability to restrict current and is expressed in percentage.
