HV HIPOT GDHG-201A Transformer Comprehensive CT/PT Analyzer (transformer frequency conversion volt-ampere characteristic tester) is a special testing instrument used for relay protection and high voltage insulation to test protection current transformers and protection voltage transformers. The instrument uses frequency conversion Technology, improve the voltage test range, reduce the weight of the whole machine, it is an ideal device to replace the existing voltammetry tester.
HV HIPOT GDHG-201A CT/PT Analyzer
Instrument Features and Functions
Transformer for protection:
1. The CT measurement process is automatically controlled, data is automatically recorded, and the volt-ampere curve is automatically drawn.
1) Automatically set the protection current and protection voltage, and automatically adjust the step.
2) Using variable frequency power supply test, the test voltage range is wide (10000V).
3) Automatically give the reference inflection point (voltage, current)
2. 10% and 5% error curves are automatically drawn.
3. Detect the transformation ratio of known current transformers and measure the transformation ratio of unknown current transformers.
4. Measure the 100% ratio difference and angle difference of the protection winding of the protection-level current transformer.
5. The PT measurement process is automatically controlled, data is automatically recorded, and the volt-ampere curve is automatically drawn.
6. Detect the transformation ratio of known voltage transformers and measure the transformation ratio of unknown voltage transformers.
7. Measure the load parameters of the secondary circuit of the current and voltage transformers.
8. 320*240 large-screen LCD display.Wiring and operation are simple.
9. Various measurement data can be stored and printed, which is convenient for users to query.
Current transformer for metering:
1. Meet the 1%-120% (S-level) specification error (angle difference, ratio difference) of measuring current transformers in accordance with the national standard point measurement current transformers.
2. Complete the measurement and display (according to the standard measurement) the standard point error (angular difference, ratio difference) under the upper limit load and lower limit load of the current transformer at one time.
3. Detect the transformation ratio and polarity of the current transformer.
