9 Jan 2008
I have a system using a star-delta close transition with resistor and capactior starter.
During the starting stage the earth leakage is about 9.6Amp! Is pretty high isn't it? The earth leakage relay is using a differential CT to measure my 3Ph 4 Wire, that is why it can detect the earth leakage during starting. After running it is back to normal zero leakage. Wire is fine and motor is fine. What could have causes the leakage current? |
