The device is a high-voltage test AV 50 / 70-3
|
1. PURPOSE
1.1. Apparatus high voltage test AV 50 / 70-3 (hereinafter & ndash; & laquo; apparatus & raquo;) for:
- Test insulation safeners (insulating rods, rubber boots, gloves, power and so on. n) variable high voltage power frequency adjustable within 0 -.. 100kV
- test power cables and insulation solid dielectrics rectified electrical voltage, as well as for testing of solid dielectrics sinusoidal electric voltage frequency of 50 Hz <. / li>
- determine the breakdown voltage of liquid dielectrics (GOST 6581-75) & nbsp;
1.2. The apparatus is designed for operation under a canopy or smokers at operating air temperatures from minus 10 & deg; C to plus 40 & deg; C, 80% relative humidity at a temperature of 20 & deg; C and atmospheric pressure 84,0 & ndash; 106.7 kPa (630 & ndash; 800 mm Hg...)
1.3.. The apparatus can be used in two ways:
- stationary,
- laptop
1.4.. To use this machine requires two operators who have permits to work on electrical installations with voltage over 1000 V
& nbsp;.
