Voltage sag is one of the major power quality problems that maybe result from networks fault and sudden increase of the load. It will result in abnormal operation or shutting down of device. Sag location is an important topic because power-quality trouble-shooting, diagnosis, mitigation policy could be constituted and mitigation measurement be carried out only after locating the voltage sag source...
Leakage current is the most important parameter in measuring electrical safety performance. A leakage current measuring system which meets multiple IEC standards is designed based on TMS320F2812 in the paper. Pretreatment amplifying circuit adopts high precision linear optocoupler HCNR201 and broadband amplifier HA7-5127-5. AD converter is the embeded 12-bit A/D in the DSP. Magnification times of...
