What is needed to test Magnetizing Current at high voltage?
An AC Interface together with the AT3600 and external power supply will be required which extend the test capability of the AT3600 up to an excitation voltage of 600Vrms and a test current of 10Arms.
MAGX Test Specification:
Test Signal Frequency Range: 20Hz to 20KHz (1MHz depending on selected CT and source)
Magnetizing current: 10uA to 10kA (low current bypass CT)
Test Voltage: 5V to 600Vac
Basic accuracy: 0.1%
