Get PriceBecause replacing a high voltage transformer requires planning for many reasons, including long manufacturing lead times that can exceed a full year, it is widely accepted that asset management, particularly of transformers, is a beneficial contribution to the operation of the grid.
Get PriceApr 21, 2020This type of current transformer is designed to non-invisibly measure current from the high voltage subsystem or where a high amount of current is flowing through the system. A current transformers job is to convert the high amount of current to a lower amount of current which can be easily measured by a microcontroller or an Analog meter.

Potential Transformers. Voltage transformers (VTs) are essentially step-down transformers with highly accurate turns ratio.
Get PriceThe electrical instruments are not directly connected to the meters or control apparatus of high voltage for safety purpose. The instrument transformers like voltage transformer and current transformer are used for connecting the electrical instruments to the measuring instruments.These transformers reduce the voltage and current from high value to the low value which can be measured by

Get PriceThis current is called short circuit current and its magnitude is very high due to zero impedance offered by the load (secondary winding is short-circuited).. Now, if we reduce the applied voltage on the transformer primary i.e. we apply a percentage of rated voltage in transformer primary, current on both windings will also reduce.
