Earth Leakage Detector
the protime's earth leakage detector can be used to sense the resistance between earth and live or dead (isolated) parts/cables. For highly critical equipment and/or their usage in hazardous environment, the body of equipment or exposed parts are earthed to avoid accidents due to fire and safety of human beings. The eld is
used to keep vigilance on these earthed parts/body. If the resistance between these two increases, it will energise to give an alarm or to terminate the process immediately.
