MEWOI2800B Wireless High Voltage Electroscope


      The MEWOI2800C wireless high voltage electroscope (with voltage and current indication) is specially designed and manufactured for checking the electricity of high voltage power line, checking the voltage of high voltage power line to ground, inductive voltage and current. The products overcome the limitations of the traditional high voltage electroscope, which can only detect whether there is electricity. This instrument can measure high voltage with respect to earth voltage at the same time as an electrical test alarm. 380V~220KV ETCR1800A Wireless High Voltage Electroscope fully covers electricity and ground voltage testing for each voltage level (380V, 6.6KV, 10KV, 35KV, 66KV, 110KV, 220KV), no need purchase multiple sets of high voltage electroscopes according to different voltage levels, which can save cost, safety, reliability and save time. It is a necessary tool for power line maintenance. In the maintenance and repair of a power line, even if the line has been disconnected due to capacitive effect, there may still be very high voltage through induction, which seriously endangers the safety of operators and the work process. An electroscope must be passed to check if the cable voltage has dropped to a safe and working voltage level.

          The MEWOI2800C wireless high voltage electroscope  (with voltage and current indication) is composed of the main receiver, detector, telescopic insulating rod, monitoring software, USB communication cable, etc. During the test, you only need to hang the detector on a bare wire with an insulating rod , the voltage value can be read on the portable receiver through wireless signal transmission. The distance of wireless signal transmission in a straight line is about 30 meters. The detector has a red LED and a buzzer, as well as other sound and light signals, which makes the test easier and more convenient. The monitoring software has real-time online monitoring, historical data query, saving, printing and other functions.
