Shock-acoustic generator with measurement type GUA-100E / P

Shock-acoustic generator with measurement type GUA-100E / P 
The impact-acoustic generator with the GUA-100E / P measurement was developed as a portable, special device of normal construction, used to locate damage to power cables and tire cables and to measure the correctness of the repair of the damaged cable.
It can be used to locate damage to cables and wires supplying mining, transport, mobile, transportable and manual devices installed in underground workings (rooms) of mines.

In a shock-acoustic generator with GUA-100E / P measurement for locating cable or wire faults
The method of using the optical-acoustic effects accompanying the impulse breakdown of the insulation with the test voltage (adjustable up to 20kV) was used in the place of damage to the conductor of the tested cable or sheath conductor. The percussion-acoustic generator with the GUA-100E / P measurement can work in the measurement and location modes.

LOCATION:
Energy from capacitor banks with adjustable voltage from 0 to 20kV through the magneto and test clamps is supplied to the tested cable or sheath conductor. The test voltage can be changed with the adjustment knob. The frequency of the pulses and their energy depend on the distance of the magneto electrodes.
MEASUREMENT:
The correctness of the repair of a damaged cable is measured by observing the current on the display of the milliammeter with an appropriately set test voltage. According to the standard, the repair cable or wire can be connected to the voltage when the leakage current is <300μA / km.
