Abstract :
The transformer is a device that can convert power from one voltage level to another voltage level. The transformer is certainly expected to work on the desired performance. Therefore, before the transformer can be used in the electric power system, it is necessary to do some testing on the circuit of the power transformer. Transformer testing conducted by SPLN D3.002-1: 2007 (Rev. SPLN 50: 1997 and SPLN 50: 1982) through several tests described in IEC 60076 are: routine testing, type testing, specialized testing, acceptance testing. One of the routine test is no load losses and load losses, the no load losses and load losses test is intended to losses on the transformer coil. The test result of the transformer being tested is good because it has a loss value of iron core and winding resistance above the test standard limit accordingly SPLN D3.002-1 : 2007 Ie for no load losses test 213,78 watt standard 210 watt Its tolerance +10 % and load losses test 1439.478 watt standard 1240 watt its tolerance +10 % ,( SPLN D3.002-1 : 2007 page 7 )
