NRHL Series Standard Current Transformer

1. Product introduction

NRHL Series Standard current transformer is used as the standard CT to test the current transformer which has lower accuracy.

2. Characteristics

1). This product is composed by primary winding and secondary winding.

2). Calibrate according to the standard current ratio indicated on the nameplate.

Check according to the standard current ratio indicated on the nameplate.

3). The standard current transformer can be carried self-calibration with current ratio of 5/5 or 1/1.

4). With wheels easy to carry and operate.
