Generation Earth Leakage Protection Relay Teaching Equipment Electrical Engineering Lab Equipment

Item No.: ETH-R
ETH-R Generation Earth Leakage Protection Relay Teaching Equipment Electrical Engineering Lab Equipment
Description
ETH-R Generation Earth Leakage Protection Relay Teaching Equipment Electrical Engineering Lab Equipment

This optional module mod. ETH-R includes a Earth Leakage Protection Relay to be used together with the on-board protection relays of Panels GCB-3 and PGP-1. In the last case, only as a leakage current sensing relay.
TECHNICAL CHARACTERISTICS:
Differential Relay
A-type differential relay, with two adjustable trip times and currents, with toroidal transformer for the cables of the lines to be controlled.
Measure and sensing the TRMS current
Adjustable tripping currents, Idn selectable: 0,03 to 3 A
Adjustable tripping times, selectable: 0.02 to 1 s (INS, SEL)
Two independent programmable relays (C1: alarm, C2: tripping)
Toroid transformer, DIAMETRO 30mm
Display: 3 colored LEDs for ON, alarm and trip
No. 2 output relay contact: 230 Vac, 6A
Test and reset button + 4 programming pushbuttons
Test rheostat mod. RCD-1
This table top rheostat, completely included in a painted metal container, allows to simulate an insulation leakage current in the range of 5 to 40 mA @ 3*400 V + N. All terminals are 4 mm safety type.
