Detailed Introduction of SGYH-S Handheld Zinc Oxide Arrester Live Tester
1. Product Introduction:
The handheld zinc oxide arrester live tester is a special instrument used to detect the electrical performance of zinc oxide arresters. It is suitable for live or outage detection of zinc oxide arresters of various voltage levels, thereby timely discovering 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 uses digital waveform analysis technology, adopts software anti-interference methods such as harmonic analysis and digital filtering to make measurement results accurate and stable. It can accurately analyze the content of fundamental wave and 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 high-speed panel printer and rechargeable battery, making it very convenient for testers to use in the field. The instrument uses a high-speed magnetic isolation digital sensor to directly collect input voltage and current signals, ensuring data reliability and safety.
2. Performance Features:
1) This device is a handheld operating instrument with a large Chinese display, easy operation, and reliable data testing.
2) Weighing only 0.5kg, it is significantly lighter than other similar instruments while having more powerful functions.
3) Simultaneously tests the total current, resistive current, deflection angle, active power, capacitive current, and 3rd, 5th, and 7th harmonic currents of three-phase arresters. It can directly evaluate the performance of the arrester (excellent, good, fair, poor).
4) This instrument can use electric field induction or wireless transmission methods to replace PT secondary wiring.
5) This instrument can directly measure resistive current without connecting to PT secondary.
6) This instrument has multiple testing methods for convenience. (PT, wireless, induction, no PT)
7) This instrument can test three phases simultaneously with automatic compensation, making it especially convenient to use.
8) Equipped with an 8000mAh large-capacity lithium battery, it can work continuously for 36 hours on a single charge.
9) High-precision sampling and processing circuits, and Fourier harmonic analysis technology ensure more reliable data.
10) The instrument uses a high-speed magnetic isolation digital sensor to directly collect input voltage and current signals.
