High-voltage tester EP8510S

cablenon-contact

EP8510S wireless high-voltage electroscope, also known as fully intelligent wireless high-low voltage electroscope, with voltage, voltage level and frequency indication, is used for high-voltage transmission line power test, high-voltage transmission line to ground voltage test, induced voltage test, etc. the instrument is composed of collector, expansion insulating pole, receiver, etc., and the power test range is 0-500kV (400V, 10kV, 35kV, 110kV, 220kV, 500kV) fully intelligent It can detect electricity. When the voltage of the bare conductor is 0-110kv, the collector can touch the test voltage and test the voltage value, when the voltage of the bare conductor is more than 110KV, the non-contact test is used, and the collector can complete the test when it is close to the conductor gradually. During the maintenance and repair of transmission lines, even if the lines have been disconnected, due to the capacitance effect, very high voltage may still exist through induction, which seriously threatens the safety of operators and operation process. It must be checked by an electroscope to see whether the voltage of the cables has dropped to the safe and operable voltage level, so no matter it is the zero line, live line, ground line, high-voltage transmission line As long as there is electricity in the line or metal conductor, it may be directly transmitted electricity, or leakage caused by insulation damage, or cross mutual inductance and electrification of the cable. The electroscope can sense its electromagnetic field and emit a beep of "beep beep beep".
