|
1. PURPOSE
1.1. Apparatus high voltage AV 50 / 70-4 (hereinafter & ndash; & laquo; apparatus & raquo;) for:
- insulation test safeners (rubber boots, gloves, power tools and the like) variables high voltage power frequency adjustable within 0 - 50kV
- testing the insulation of power cables and solid dielectrics rectified electrical voltage to 60 kV, as well as for testing of solid dielectrics sinusoidal electric voltage frequency of 50 Hz
- determine the breakdown voltage of liquid dielectrics 50 Gts.do50kV voltage frequency. (GOST 6581-75)
- Measurement of leakage current test objects (safeners, fuses, etc.)
& 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:
