For this reason, no load losses are very important for operational economy. No-load losses are also used in the heating test. The measured losses depend heavily on the applied voltage waveform and frequency. The last two of them are very small in value and can be ignored. So, only the iron losses are considered in determining the no-load losses. If the supply voltage is different than sinusoid, the measured no-load losses have to be corrected by a calculation.

If the readings of both voltmeter are equal, there is no need for correction. In this way, the foreseen induction is formed and as a result of this, the hysteresis losses are measured correctly. What is the Eddy Current? During no-load loss measurement, the effective value of the no-load current of the transformer is measured as well. For this reason, the core has to be demagnetised. The phase angles between voltages and currents may be different for each of three phases.

For this reason, the wattmeter readings on each of the three phases may not be equal. Sir why transmission are done in 11,22,33,132,220kv why this odd number of multiple of 11. When a three-phase transformer is tested, the voltages shall be measured between line terminals, if a delta-connected winding is energized, and between phase and neutral terminals if a YN or ZN connected winding is energized. PT primaries neutral and we can ground them together. I will be so grateful if i get a feedback from you. Sir please tell the clear difference between the no load test and harmonics test on no load conditions of distribution transformers.

Whether the harmonics measurements can be made on no load or not? Why the wire size of the fusewire in structure is so small? How can it possible to conduct high current? 80 MIA had faced external School from the load side . My question is the supplier need to do the following tests sc impedance . No load losses with reduced voltage . Click here to cancel reply.
