The ZCT408 is a customizable zero sequence transformer with a rated current of 100A and a resistance of 13±3Ω. It withstands up to 2500Vrms, outputting 25-30mV. Its error arises from iron core reluctance, consuming current for excitation, causing a vector difference between primary and secondary currents, including ratio and phase angle discrepancies.
ZCT407 is a customizable transformer for EV charging, with specifications like 630A rated current, 52±5Ω resistance at 25℃, and a 2500Vrms dielectric voltage. It enables zero current sensor protection by monitoring unbalanced currents and detecting single-phase grounding faults, enhancing the safety of electrical systems.
The ZCT406 is a customizable Zero Phase Current Transformer rated at 400A DC with 70±3Ω resistance and can withstand 2500Vrms. It operates on the principle of Kirchhoff’s current law to provide ground fault protection, with no secondary output during normal conditions and activating during faults to trip the power supply.
