Product description

The short-circuit and ground fault indicator MEg61.4+ (hereinafter MEg61.4+ indicator only) stems from well-proven functions of the previous ground fault indicators of MEg61.4 series which were supplemented with new recording functions. Thus one unit incorporates the ground fault indicator for MV levels where, except for identification of faults and registration of fault states, continuous monitoring and long-term recording of
monitored quantities is performed as well.
The MEg61.4+ indicator identifies the segment of overhead line in which a ground fault or a short-circuit (overcurrent) occurred. The MEg61.4+ indicator can be used for outdoor installation on MV overhead line poles or for installation in internal environment with cable MV lines. Bolted, arc and low impedance ground faults and all types of shortcircuits are indicated. It is primarily designed for use in compensated MV distribution networks; however, it can be used in MV distribution networks with grounded neutral.
The MEg61.4+ indicator measures and records the data related to voltages, currents and powers in the non-destructive electronic memory in preselected intervals.
Ground fault records consist of the curves containing 10 ms values and the curves containing individual samples of basic quantities.
