3�5�10�- Leakage Current Connection - Circutor Computer SMART III 6 Instruction Manual

3�5�10�- Leakage current connection, I
To measure the leakage current, an earth leakage transformer must be used, such as WGS.
The leakage current transformer must be connected such as to measure the current of the capacitor
bank. This will detect any leakage in the capacitors of the capacitor bank.
Note: The earth leakage transformer must have a ratio of 500 turns. The maximum leakage current
that the device can measure correctly is 1.5A AC, even though the maximum input is 5A AC via the earth
leakage transformer.
