GDHG-6802 transformer calibrator Product Description:

At present, the traditional transformer test methods are mostly used comparing the measured difference, that is, when the transformer during the test, will be seized transformer secondary connected load (load cases instead of commonly used), and standard transformer ratio is compared with, (booster) is provided to both the primary current (voltage) by the up-flow, and the second difference between the two flow (differential) input signal calibrator, the calibrator is measured relative to the standard mutual inductance transformer seized the error. This test method, a large current (voltage) power supplies, transformers and load box with standard variable ratio. When a current is greater than 1000A, a voltage higher than 110kV, the power supply capacity of up to tens of kVA, bulky and difficult wiring in the field test transformer inconvenient.

Instrument is based on a detailed analysis of the mathematical model developed on the transformer transformer tester. During transformer test, it does not require high-current power supplies and standard transformer and large load box, just to bring the instrument can be measured according to national standard differential current transformer ratio difference and angular, but also measuring the current 1% 120% of the difference between any percentage ratio and angle difference; direct measurement of current and voltage transformer turns ratio; worse than the qualitative difference and angle can be measured voltage transformer; field measurement of the actual current and voltage transformers secondary load, test particularly convenient. Using high-precision instrument, automatic linear regulator of DC and AC power supply; high-speed, high-reliability digital processing module; high accuracy, high stability of the pre-measurement circuit ensures high accuracy and stability of the measurement instrument. In addition, the instrument also has a user-friendly interface, and operating tips wiring, and save any measurement parameters and measurement results print function.
