Clip-on CT's Electronically compensated clip-on CT's up to 100 A

The electronically compensated clip-on CT's has been designed for the measurements of currents in the range of 10 mA up to 100 A. Their small size makes them particularly handy when working in cramped spaces such as me-ter installations or circuit breaker boards.

Application

The clip-on CT's are suitable for following de-vices:

Portable Reference Standards: PRS 400.3 / CALPORT 300

Precautions for use of electronically compensated clip-on CT's

Install the electronically compensated clip-on CT's to test circuitry

Disconnect the electronically compen-sated clip-on CT's from test circuitry

Step 1

Connect the elec-tronically compen-sated clip-on CT's to the instrument.

Step 1

Disconnect the elec-tronically compen-sated clip-on CT's from the test circuitry.

Step 2

Connect the supply of the instrument with the auxiliary or measuring voltageand start up the in-strument.

Step 2

Switch off the instru-ment and disconnect them from the aux-iliary or measuring voltage.

Step 3

Connect the elec-tronically compen-sated clip-on CT's to the test circuitry.

Step 3

Disconnect the elec-tronically compen-sated clip-on CT's from the instrument.

Never take away the power supply of the instrument or unplug the CT-connector, during the clip-on CT's are

connected to cables with current flowing.

If these precautions are not followed, the instrument can be damaged
