KDYZ-30kV zinc oxide arrester DC parameter tester is specially used to detect the internal defects of the non-gap zinc oxide arrester MOA valve with poor performance for 10kV and below power systems. According to the provisions of 16.1 in DL/T596-2021 Preventive Test Procedure for Power Equipment and GB /T 11032-2020 AC Gapless metal oxide Arrester, Before the annual thunderstorm season and when necessary, the power plant and substation should do the metal oxide arrester 1mA DC voltage (U1mA) and 0.75 U1mA leakage current detection. According to the measuring procedure, the ambient temperature and relative humidity during the test should be recorded. The instrument can automatically measure the ambient temperature and relative humidity.
 
The instrument combines DC high-voltage power supply, measurement and control system to reduce the volume and weight of the instrument. It is suitable for testing under various conditions such as substation, repair workshop, manufacturer and laboratory, etc. The instrument replaces the traditional heavy test instrument and test method, and is the commonly used equipment for on-site inspection of power system and zinc oxide arrester production plant.
 
The instrument can be operated by touch screen, remote control, mobile phone Bluetooth APP wireless operation, RS232/RS485 connection operation, external IO wire control operation and other measurement methods, with high flexibility.
