Up to 12 timing channels.

Built –in thermal printer.

Power-frequency parameters of long-distance extreme-high-voltage (EHV) and ultra-high-voltage (UHV) transmission lines are the basis of power system modelling and analysis, but these parameters are especially difficult to accurately measure due to the reactance-dominated nature and strong external interference.

HANY LPT15 series transmission line analyzer using a new variable frequency technical to measure the parameters.

The risk of overheating is becoming more serious due to the fact that today’s distribution networks have to carry heavier loads. Checking contact resistance at regular intervals detects faults before they cause overheating. Contact resistance tester is used to measure contact resistances of circuit breakers, disconnecting switches, earthing switches, bus joints, bushing contact joints and welding joints. Also for any low resistance measuring application. The tester provide 100A DC current, and the voltage measurement gets the voltage of tested object.The method of calculate resistance according to Ohm’s law. (R=U/I)
