High Frequency Current Transformer 39mm Clamp - Beijing Kanggaote Instruments and Equipment

Product introduction

High Frequency Current Transformer 39mm Clamp is an inductive sensor for Partial Discharge detection. It can provide a very accurate, non-contact, non-destructive PD signal for all kinds of PD detectors. It is suitable for on/off line PD tests on many electrical systems such as transformers, reactor, cables, and rotating machines.

Cautions
▪ Do NOT let the sensor contact permanent magnet material for a long time.
▪ Make sure lock tightly before the test.
▪ Mare sure the current direction is the same as the arrow pointing in the sensor.

Test Response

▪ HV/MV CABLES:
Under 1000kV transformer, reactor, bushing,cables and rotating machines;Under 110kV cables.
▪ Connection:
It can be fixed directly to the grounding connection of the system under test without
disconnecting.
▪ Online PD Monitoring:
HFTC can do PD measurement without disconnection.
It can be carried out without an outage.
▪ POWER SUPPLY FREE:
HFCT sensors don’t need any power supply,just need a connection with the main device.
