Abstract :
The paper discusses a load testing facility to test both single and three phase loads up to 10 kVA for their susceptibility to power quality disturbances. The disturbances of concern are low frequency with components up to 1 kHz and includes lower frequency harmonics and interharmonics, sags, swells, unbalance, overvoltage, undervoltage, flicker, and frequency excursions. To deal with the above, the load testing facility includes (i) a waveform generator, (ii) a double chamber calorimeter for accurate measurement of losses, and (iii) a computer based instrumentation system. Some example applications of the facility are given
