The dielectric loss test is a specialized instrument used to detect the electrical performance of zinc oxide arresters. This instrument is suitable for live or outage testing of zinc oxide arresters at various voltage levels, thereby promptly identifying dangerous defects such as internal insulation moisture and valve plate aging. The instrument is simple to operate and convenient to use. The entire measurement process is controlled by a microcontroller. It can measure the total current, resistive current and its harmonics, power frequency reference voltage and its harmonics, active power, and phase difference of zinc oxide arresters. The large screen can display the real waveforms of voltage and current. The instrument utilizes digital waveform analysis technology, automatic frequency conversion technology, harmonic analysis, digital filtering, and other software anti-interference methods to ensure accurate and stable measurement results. It can accurately analyze the content of the fundamental wave and the 3rd to 7th harmonics, and can overcome the influence of inter-phase interference to correctly measure the resistive current of side-phase arresters. This device is equipped with a rechargeable battery, making it very convenient for field use by test personnel. The instrument uses a unique high-speed magnetic isolation digital sensor to directly collect input voltage and current signals, ensuring data reliability and safety.
