iCT1 Current and Voltage transformer test set

iCT1 is a fully automatic Current and Voltage transformer test set, especially designed for testing CTs, VTs and Combined Transformers. He`s grants a faster testing, thanks to its 5-TAP switchbox which allows to connect directly up to 5 taps, in this way the connection of the device is made only one time and without the need of any further manual operation.

Manufactory: ISA - ALTANOVA GROUP (Italy).

Features
  • Designed to test Current, Voltage and Combined transformers
  • Time saving testing: only 1 set up connection to perform all the tests
  • Main tests performed: Ratio & Phase Error, Excitation, Resistance, Accuracy, Burden
  • 5-TAP integrated switchbox describing the behavior of the CT
  • Able to test CT with saturation voltage up to 2kV and till 30kV applying DC indirect method
  • Integrated demagnetizer
  • CT Explorer function: able to find the nameplate data of the CT
  • Compact and lightweight
  • Patented technology

High AC voltage

The high AC voltage output up to 2kV is coming from a transformer that provides to insulate the outputs from the power supply.
