Earth Leakage Detector

We are a prominent earth leakage detector supplier in india. All the channels of the earth leakage detector continuously monitor the insulation of the cable and an alarm is actuated along with a visual indication when the leakage value drops to the preset value. Each such fault is recorded on a 6 digit counter. Fault detection can be set in between 2k-1m. The audio alarm is common for all channels while the visual indication is separate for each channel. the basic earth leakage detector comprises of 4 channels for use on signaling circuits of 110v69v24v12v in ac or dc, or as required by the purchaser. In case of requirement for less number of channels, unused channels are covered with dummy plates while the inner wiring remains the same and these dummy plates can be replaced by channel modules if and when required in future. For more than 4 channels, say 8 or 12 channels, basic unit without meter can be connected as switching arrangement is provided for connecting such units. suitable interconnecting cables provided with the earth leakage detector. The earth leakage detector also consists of an insulation resistance meter, which can be connected to any individual circuit to indicate the actual value of the insulation resistance of the signaling circuit during unenergised condition i.e. Off-line condition. technical specifications
