PTA-2000 Portable Voltage Transformer Analyzer is also called Voltage Transformer Analyzer and Voltage Transformer Tester.


Portable Voltage Transformer Analyzer is a special instrument used in the power industry for transformer testing. The voltage transformer analyzer is mainly used to detect the excitation characteristics, ratio, polarity, and secondary winding resistance of the voltage transformer.

Functional and technical features of portable voltage transformer analyzer:


1. A single voltage transformer analyzer can realize the error test of the voltage transformer without the need of resonant boosting device, standard voltage transformer, load box, calibrator and other equipment, which greatly reduces the workload of the field calibration error.


2.the test range is wide, can test the voltage level of 6kV ~ 800kV electromagnetic voltage transformer.


3.the internal use of 0.01 standard voltage transformer, using the differential method to test the low voltage error of the transformer, using the inter-frequency test technology, convert the nonlinear error of PT at 50Hz, and finally get the error of the transformer.
