MEWOI2820-380V to 500kV non-contact line voltage tester, non-contact wireless electroscope
Introduction
| MEWOI2820 non-contact high voltage electroscope, also known as non-contact acousto-optic electroscope, is specially designed and manufactured for high voltage transmission line electroscope. The product is used for on-site inspection of the high voltage line, detecting the voltage level in the high voltage system, checking the faults of the high voltage line, repairing neon lamps, high pressure sodium lamps, checking the induced voltage, and checking the residual high voltage or induced voltage, etc. The product consists of a detector high voltage and telescopic insulating rod. It uses non-contact induction technology and does not require contact with a charged body, which ensures the safety of the operator. The electroscope has a red LED and a buzzer sound and light signal, easy to identify, 9 voltage gears cover different voltage levels, suitable for a variety of high voltage systems, no need to purchase multiple sets of high voltage electroscopes according to different voltage levels, reducing costs. The protection level reaches IP65, which allows it to be used both indoors and outdoors. The electroscope uses an adjustable interface to connect with the insulating rod, the connection is reliable, and the operation is especially convenient. The operation is simple, safe, reliable, time-saving and fast. It is a safe, practical and convenient new power tool for electrical inspectors. It is an essential tool for the maintenance of railway and power lines.
