Receiver P-806
|
1 DESIGNATION
1.1 P-806 receiver is:
a) to search tracks, damaged areas of the interphase insulation and depth of the high voltage power cables induction method; < p> b) for fault location high voltage power cables acoustic method.
c) for detecting leaks, insulation of underground cables power without metal netocrystalline membrane potential method using a contactless potential sensors.
1.2 searching receiver induction method should be used in conjunction with an additional generator of any form of continuous oscillation frequency 1024 Hz 2 and
2048 4Hz, providing loads in the range of 0.5 to 200 ohm output . capacity not less than 200 W (e.g., GZCH-1000 GZCH-2500)
searching receiver acoustic method should be used in conjunction with additional gene-Rathore powerful pulse voltage of 5-10 kV and a pulse energy of 150 - 1000 J, the following interview, the scrap in a slightly to seconds (e.g., GAUV-5).
1.3 The receiver is intended for operation in the field in the ambient temperature range from -20 to + 40C, relative humidity of 85% and a pressure of from 600 to 800 mm Hg . v.
NOTE. Lower limit of the working temperature is determined by the working capacity at this pace-ture power source and a liquid crystal display
