CT/PT Transformer Characteristics Comprehensive Tester

Production Description:
HZVA-402mutual inductorcomprehensivecharacteristic tester is a automatic CT, PT characteristic tester. Test includingCT 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 inductortest and voltage mutual inductortest.
Product Features:
Protective mutual inductor:
1.Automaticcontrolling during the CT test process, automatic recording data and scanningvoltammetry 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 fieldrequirements
2.Automatically drawing 10% and 5% error curve
3.Can detect known current mutual inductorand non-known current mutual inductorratio
4.Automatic controlling during the PT test process, automatic recording data and drawing voltammetry curve
5.Can detect known voltage transformer and non-known voltage transformer ratio
6.320*240 largeliquid crystal screen display. Easy to connect and operate
7.Can save and print all test data, convenient for checking
Metering current mutual inductor:
1.Meet the national standard point of1%-120% (S level) regulated measurement error(angle difference and ratio difference) of testing current mutual inductorand arbitrary point of the current mutual inductor.
2.Meet the standard point of1%-200% (S level) any error(angle difference and ratio difference) oftestingcurrent mutual inductorand 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.
