Installation proboyny universal UPU - 10 is intended for test of isolation of the electrotechnical equipment and materials by the variable sinusoidalnymnapryazheniye with a frequency of 50 Hz and the straightened tension of negative polarity regulated within 0 - 10 kV with output current to 100 ma
Scope – the electrician and the power engineering specialist.
Thanks to the raised output current installation can be used for test on an alternating voltage of isolation of windings of large electrical machines. With success it can be used for test of protective equipment for the corresponding tension (gloves, etc. ), and also for a charge of capacitor stores of energy.
1.2 Installation is calculated for operation in rooms or under a canopy at working values of air temperature from plus 5 °C to plus 40 °C, relative humidity to 80% at a temperature plus 20 °C and the atmospheric pressure of 84,0 - 106,7 kPa (630 – 800 mm Hg).
1.3 Food – a single - phase network of sinusoidal alternating current of 220±20 V, with a frequency of 50±1 Hz.
1.4 Installation is served by one operator with the right of work on installations with tension higher than 1000B.
