Circuit Breaker Test System UPA-6

Testing UPA-6. The circuit breaker tester UPA-6 produced load in conjunction with the current transformer 10000/5А, connected with four 1-metre long current leads with a cross-section of 110 mm². Current on the transformer was measured with a comparator. Current adjustment was done with the voltage transformer RNO-80. Voltage on the voltage transformer RNO was measured with a voltmeter, current was measured with a clamp. We set 6 kA, compared with the readings of reference measuring instruments and allowed 1 minute for the overheating protection to be activated. http://www.kep.ua/en/device/10/upa-6/
