Product introduction

It is a new automated testing equipment, it uses advanced electronic technology, the transformer is taken directly polar decomposition of the error signal, and after appropriate after the operation, the transformer points, phase error , quadrature error in the digital display. HGQB-C transformer calibrator is simple, intuitive readings, measure quickly, can reduce energy consumption, reduce labor intensity; small size, light weight, easy to carry and field testing; instrument can be fixed at 5% Operating current (voltage) under testing; otherwise required Electric Co., Ltd., Wuhan NARI can produce detect S-class current transformer and the secondary voltage of the voltage transformer calibrator 100/3V, then 1% of the rated instrument can measure the current transformer operating current the error; instrument in the detection process can be easily carried from the school at any time to ensure the accuracy of the instrument; critical components using imported components, stable and reliable quality, widely used in metering, power supply and other departments and transformer manufacturers, is to carry out transformer testing the ideal instrument.

Alternative name
Transformer tester, PT calibrator, CT calibrator

Precautions
1,Wiring according to the instruction correctly.
2, If you are unclear , please phone manufacturers, ask before the operation .
3, Make sure determine calibrator shutdown, cut the machine and cotrol box power before wiring or stitches ,,
4 , Double-check before starting , make sure the wiring is correct , reliable wiring , ground connections ;
5 , During the current transformer test , note the secondary can not be open , including the inability to easily switch current load box stalls ;
6 , Voltage transformer test , note the secondary can not be short-circuited. Requirements must be strictly in accordance with wiring diagram wiring, and reliable grounding , and should enclose the test site , retain sufficient safe distance , to prevent others from straying into the accident occurred ;
7 , Must satisfy nameplate required, put in right gear, use high current wires and dedicated test line when do current transformer test ;
