The difference between a current transformer and a voltage transformer in electrical systems
Jun 06 , 2023
A current transformer and a voltage transformer are two different types of transformers used for different purposes in electrical systems. Here's a closer look at each: Current Transformer: A current transformer (CT) is designed to measure electrical currents in a circuit and step them down to lower levels for measurement or protection purposes. It consists of a primary winding and a secondary win...

Can current transformers be used for high voltage applications?
Jun 06 , 2023
Current transformers are primarily designed for measuring and monitoring electrical currents in various applications. However, their usage can be extended to high voltage applications when used in conjunction with voltage transformers. In high voltage systems, measuring the current directly can be challenging and unsafe due to the high voltages involved. Therefore, current transformers are employe...

Current transformer structure principle
Nov 10 , 2022
1, The ordinary current transformer structure principle is relatively simple, by the mutual insulation of the primary winding, secondary winding, core and frame, shell, terminals and other components. Its working principle and transformer is basically the same, a winding turns (N1) less, directly in series in the power line, a load current (I1) through a winding, the alternating flux induction gen...
