Abstract: In the process of commissioning a 2*600MW Coal-fired power plant, The secondary circuit voltage test of # 1 main transformer voltage transformer was carried out. During the test it was found that the vacuum switch MCB 9 of the third winding was not closed,but A voltage is generated at the non-charged side of the switch. After a number of experimental analysis,the problem was found and solved. The secondary circuit voltage test of # 1 main transformer voltage transformer is carried out again. The test results are correct,ensuring the commissioning process
Key words: electrical commissioning, voltage transforme, secondary circuit
