Description
Overview
GAOTek High-Voltage Transmission Line to Ground No Voltage Tester 500kV ensures safety during maintenance by accurately detecting voltage absence. It offers reliable measurements without physical contact, minimizing risks in high-voltage environments and enhancing work efficiency.
Features
- EP8510S Wireless High-Voltage Electroscope: A fully intelligent wireless high-low voltage electroscope for power tests in high-voltage transmission lines
- Instrument Composition: Consists of a collector, expansion insulating pole, and receiver
- Detection and Testing: Detects electricity with voltage test capabilities. Allows direct contact testing up to 110 kV. Enables non-contact testing for voltages exceeding 110 kV
- Importance of Electroscope Testing: Essential for maintenance and repair of transmission lines. Checks cable voltages for safe and operable levels. Ensures operator safety by identifying residual voltage and potential leakage
- Collector and Receiver Functionality: Collector connects to a metal probe hook for easy hanging on bare wires below 110 kV, saving operator physical strength. Receiver features a 2 true color LCD screen displaying voltage level, value, and frequency
- Wireless Operation: Enables convenient testing and monitoring of electrical parameters. Provides a wireless receiving distance of approximately 100 m.
- Wide Applications: Suitable for substation, power station, railway, fire department, industrial and mining enterprises, monitoring stations, and electrical maintenance departments for electrical detection and field electric operations
