in the EP8510S ?

General Information:

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".
The collector connected to the metal probe hook can be hung on the bare wire below 110kV for testing, which can save the physical strength of operators. The collector connected to the metal probe can be used to check the power of the hole of the two charged indicator.
The receiver adopts a 3.5-inch true color LCD screen, which dynamically displays the voltage level, voltage value and frequency on the same screen. It is clear and intuitive. The wireless receiving straight-line distance is about 100m.
The insulating rod is light and flexible, moisture-proof, high temperature resistant, impact resistant and highly insulated. It is widely used in substation, power station, railway department, fire department, industrial and mining enterprises, monitoring station, electrical maintenance department for electrical detection and field electric operation.

Note: the range of the direct contact test voltage of the bare conductor is 0-110kV. When the voltage of the bare conductor exceeds 110kV, the test voltage cannot be contacted and the non-contact test can be performed, for the test voltage of unknown voltage level, the non-contact test must be used first.

Induction intensity

During high-voltage power test, with the strength of the induced electric field, the electroscope will automatically adjust the 2kV, 20kV and 110kV gears, which are suitable for the places with dense lines. The 2kV gear is the default when the machine is started, and the induction is the strongest

Overhead line volt

The bare conductor below 110kV can be tested by direct contact; the bare conductor above 110kV must be tested by non-contact method; it can also be directly hung on the line with intact insulation sheath above 110kV for testing

Contact electro test

Contact electro test: when the collector is connected with a metal hook or probe, the metal hook or probe shall contact the bare wire to ensure the accuracy of power test and voltage test

Beep prompt

When the induction voltage or detection voltage is higher than 20V, the internal buzzer of the collector will send out the beep of "beep -- beep -- beep --" to remind the safety
