Operating Principles.
Earth Leakage Tests.
The testers may be used to check the trip point (Test 1) of the ECLB or the trip time (Test 2). Test 1 is normally used on instantaneous ELCB s while Test 2 is normally used on inverse and fixed time-delay ELCBs.
Test Procedure
Test 1 instantaneous ELCBs A ramp current, increasing at approximately 12 mA/s is introduced between L and E and the point at which the ELCB trips is recorded. To save time and reduce energy dissipation, the starting point of the ramp may be selected. Test 2 - Inverse and fixed time delay ELCBs. A constant current is selected and injected between L-E and the tripping time is recorded. |
Model 2820 Earth Leakage Tester, ELCB Tester is easy to use. It indicates tripping Phase Angle, operates in Voltages from 100V to 450V L-E, Checks ELCB Trip Time and Trip Point (Sensitivity) |
