Zinc oxide arrester DC parameter testing machine

Type: ZC-711
         The zinc oxide arrester DC parameter tester is specially used for detecting the internal defects of the MOA valve of the gapless zinc oxide surge arrester for power systems of 10 kV and below, according to the "Procedure Test Procedures for Power Equipment" 4.4 of DL/T596-1996 It is stipulated that the power plant and substation should test the leakage current of DC 1mA (U1mA) and 0.75 U1mA for the metal oxide arrester before and during the annual thunderstorm season.

         The company has improved the instrument according to the field measurement requirements, and combines the DC high voltage power supply, measurement and control system to reduce the volume of the instrument and reduce the weight. The operation setting is user-friendly, remote remote measurement is realized by remote control, and the automatic measurement environment temperature function is added according to the measurement procedure. With large-capacity memory, 50 sets of test data can be stored, and power failure is not lost. Equipped with a high-speed thermal printer greatly improves the printing speed of test results. It is an indispensable equipment for on-site inspection of power systems and zinc oxide arrester manufacturers.
