MEWOI2800B Wireless High Voltage Electroscope


          MEWOI2800B Wireless High Voltage Electroscope (with voltage indication)is specially designed and manufactured for high voltage transmission line electricity inspecting, high voltage transmission line  voltage to earth, inductive voltage and current test. The products break through the traditional high voltage electroscope limitation which just can only detect whether there is the electricity. This instrument can test high voltage to earth voltage at the same time of electricity testing alarm, ETCR1800A Wireless High Voltage Electroscope electricity testing voltage level 380V~220kV, completely covers the electricity testing and ground voltage test of each voltage level(380V、6.6kV、10kV、35kV、66kV、110kV、220kV), no need to purchase multiple sets of high voltage electroscope according to different voltage levels, which can save cost, safety, reliability and save time. It is a necessary tool for power transmission line maintenance. In the maintenance and repair of the transmission line, even if the line has been disconnected, due to the capacitive effect, there may still exisit very high high voltage through with induction, which seriously threatens the safety of the operators and operation process. It is necessary to pass the electroscope to check whether the voltage of the cable has been reduced to a safe and operable voltage level.

          MEWOI2800B Wireless High Voltage Electroscope (with voltage indication)consists of host receiver, detector, telescopic insulation rod, monitoring software and USB communication cable etc. During the test, you only need to hang the detector on the bare wire with insulation rod, the voltage value can be read on the handheld receiver through by wireless signal transmission.The wireless signal transmission straight-line distance is about 30 meters. The detector has red LED and buzzer and other sound and light alarms, making the test easier and convenient. Monitoring software has online real-time monitoring, historical data query, save, print and other functions
