High Frequency Current Transformer 39mm Clamp
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.
HV/MV CABLES:
Under 1000kV transformer, reactor, bushing,cables and rotating machines;
Under 110kV cables.
Online PD Monitoring:
HFTC can do PD measurement without disconnection.
It can be carried out without an outage.
Connection:
It can be fixed directly to the grounding connection of the system under test without disconnecting.
POWER SUPPLY FREE:
HFCT sensors don’t need any power supply, just need a connection with the main device.

Based on the past cooperation, we sent our HFCT sensors to the Megger, Omicron, IPEC to evaluate its functions, all of them speak highly of our HFCT sensor.
Megger had took the lead with us a batch of purchase order, the cooperation with other companies also in progressing.
The relevant data are as follows:
HFCT Test Report from IPEC
