3.3 How to attach the Current Transformer (CT)

・

Use CT that the secondary side current is 5A or 1A, the rated burden 0.5VA or more.

・

One CT is needed for 1 unit when measuring 1P2W (2 CTs for 2-circuit, 3CTs for 3-circuit). Two CTs

are needed when measuring 1P3W/3P3W. Three CTs are needed when measuring 3P4W.

Using all CTs for one unit should be the same.

・

Use the applicable wire, or it might cause a breakdown, burnout or electric shock.

・

When connecting CT, connect the secondary side to the terminal of the main unit first, and after that

wire the primary side to a load electric wire. Incorrect order might cause an electric shock or break CT.

・

The CT has polarity. Wire correctly according to the K and L marks.

Wrong direction can’t measure

correctly.

･

If there is some distortion by harmonic or waveform, it may not measure correctly.

Please check with the actual system before adopts it.

・

Separate the wiring (strong electric part) of the measured voltage input terminal (operating power

supply terminal) from the CT cable. It may not satisfy the accuracy due to noise.

DANGER

●

Never open the secondary circuit of CT under applying current to load.

●

Never remove the terminal block under applying current to load.

Will cause electric shock or breakdown CT
