High and low voltage current transformer ratio tester

● High and low voltage current transformer ratio tester is a new type of electricity inspection equipment for high voltage metering users. It can detect the transformation ratio and polarity of the current transformer used in the metering device at and below 35KV without changing the power supply, so as to effectively prevent the high-voltage metering user from replacing the high-low voltage current transformer or the nameplate of the current transformer and changing the current transformer. The polarity of the secondary line achieves the electricity stealing behavior with less billing; ● It can measure the transformation ratio, polarity and phase-to-phase correspondence of 35KV and below high and low voltage current transformers; ● It can measure the current amplitude of high and low voltage lines up to 35KV; ● Standard 20A clamp, optional 100A, 500A, 1000A clamp or 0-600A flexible clamp meter, with a low-voltage retractable operating insulating rod. ● Large-capacity lithium-ion high-efficiency rechargeable battery, continuous work for 10 hours; ● Closed jaw design greatly improves the accuracy compared with open jaw design ● Long U-shaped jaws, the width of the measured object can reach 50mm; ● Telescopic insulation rod, easy to carry; ● Graphical wide temperature, wide viewing angle liquid crystal, large screen display, which can be seen clearly under low temperature and strong sunlight.
