4.2 High Frequency current transformer measurement

(Mainly measure transformer inside partial discharge)

1. High frequency current transformer connection

Use BNC-BNC cable to connect to the tester CH1 channel BNC port, the other end to

the high frequency current transformer BNC end.

High frequency current transformer connection

2. Tester settings

Open the tester, press and select the current channel to CH1, Press” MENU” key, then

press F1 key to select “ discharge test” as HFCT, press F2 Key to set” output voltage”

and “ unit”. When test the high frequency current transformer it would require output

voltage.

3. Start measurement

Press” AUTORANGE” Key till the light is on to green, then the tester is about to

measure.
