Protective Mutual Inductor Comprehensive Characteristic Electrical Testing Machine

Protective Mutual Inductor Comprehensive Characteristic Electrical Test Equipment

Production Description:

HZVA-402 mutual inductor comprehensive characteristic tester is a automatic CT, PT characteristic tester. Test including CT volt ampere characteristic test, PT volt ampere characteristic test, CT ratio and polarity. It is a special test device for relay protection and high voltage isolation of current mutual inductor test and voltage mutual inductor test.

Product Features:

Protective mutual inductor:

◆ Automatic controlling during the CT test process, automatic recording data and scanning voltammetry curve.

1) Automatically set protection current and protection voltage, automatically adjust stepping

2) Can test 5 groups current, voltage value(voltage under appointed current or current under appointed voltage)

3) Automatically give the reference turning point(voltage and current)

4) 220V and 380V power source, meet field requirements

◆ Automatically drawing 10% and 5% error curve

◆ Can detect known current mutual inductor and non-known current mutual inductor ratio

◆ Automatic controlling during the PT test process, automatic recording data and drawing voltammetry curve

◆ Can detect known voltage transformer and non-known voltage transformer ratio

◆ 320*240 large liquid crystal screen display. Easy to connect and operate

◆ Can save and print all test data, convenient for checking

Metering current mutual inductor:

1. Meet the national standard point of 1%-120% (S level) regulated measurement error(angle difference and ratio difference) of testing current mutual inductor and arbitrary point of the current mutual inductor.

2. Meet the standard point of 1%-200% (S level) any error(angle difference and ratio difference) of testing current mutual inductor and arbitrary point of the current mutual inductor.

3. One time complete measurement and display(measurement in accordance with standard ) of standard point and random point error(angle difference and ratio difference) of the upper limit load and the lower limit load of the current mutual inductor.

4. One time complete measurement and display of standard point and random point error(angle difference and ratio difference) of two sets of the actual load of the current mutual inductor.

5. Detect the ratio and polarity of current mutual inductor.
