Step and contact voltage measurement device - HT2055
The HT2055, generally composed of a station and a meter-designed model, is generally designed to perform step-contact voltage measurements on electrical installations involving HV power station (TN system, electrical substation) with rated test currents of up to 50A in accordance with the international guidelines/standards. Both of these units, with an initially synchronized time and current, are capable of exactly calculating step as well as contact voltage values through applying the real test current measured by the station. In addition, an internal DPS filter is responsible for the automatic compensation of noise voltage disturbances, which are affecting the measuring circuits. The instrument also enables the measurement of earth resistance via three-wire method/4-wire Wenner method.
