Device for locating fault POMZ
Designation:
-FIND current leaks to earth voltage overhead transmission lines from 6 to 35 kV and determining damaged line taps;
-FIND specific location (the support) with leakage current to ground;
underground cable route -proslezhivaniya voltage of 6 kV to 35;
-proslezhivaniya runs underground cables and any voltage detection circuit in place of the cable when connecting the sound generator frequency 550Gts
specifications:.
to -works transmission lines of different voltage;
- range of recorded leak current -30A 0.1;
-provides detect faulty lines near the substations;
to-instrument remains serviceable woodland;
is the defining line of the leak and in case the cable feed to the line;
-Duration battery life for at least 20 hours;
-registriruet leakage current away from the 5 to 20 meters from the damaged section of the line.

SAFETY AT WORK IN THE ZONE VOZDUSHNYHLINY POWER!
operation:
1. Determining the presence of faults in the line.
apparatus positioned in a horizontal plane, the device axis oriented perpendicular to the line. sensitivity control set to the far right. As we approach the faulty line reading devices will increase and will reach at least minus 5 dB. At the same time to shine the light failure indicator lines.
DO NOT CROSS THE LINE malfunction within 1 ohm from the support!
2. Support Definition with leakage current to the ground.
instrument axis is parallel to the line. Moving distance (6-25) from the line m, watch the indicator readings. Opposite the damaged bearing testimony of the device will increase.
