The receiver for searching for faults in P-806 cables is intended for:
- to search for the route, places of damage to the interphase insulation and the depth of the high-voltage power cables by the induction method;
- to search for places of damage to high-voltage power cables using the acoustic method.
- for detecting leaks in the insulation of underground power supply cables that do not have a metal sheath, a potential method using non-contact potential sensors.
When searching by the induction method, the receiver must be operated in conjunction with an additional generator of continuous oscillations of any form with a frequency of 1024 ± 2 Hz and 2048 ± 4 Hz, providing an output power of at least 200 W in the load range from 0.5 to 200 Ohm (for example, GZCH-1000, GZCH-2500).
When searching by the acoustic method, the receiver should be operated in conjunction with an additional generator of powerful pulses with a voltage of 5-10 kV and an energy in a pulse of 150-1000 J, following with an interval of several seconds (for example, GAUV-5).
The receiver is intended for operation in field conditions in the range of ambient temperatures from minus 20 to +40 o С, relative humidity up to 85% and pressure from 600 to 800 mm Hg. Art.
NOTE. The lower limit of the operating temperature is determined by the operability at this temperature of the power supply and the LCD.
