The RST 25 controls the phase shift. If there is a phase failure during operation the angle from the feedback voltage is 30℃ and the RST 25 recognizes this failure.
Features:
- ZAHRA RST-25 Voltage Relay Three Phase A+ Quality
- Electronic Voltage Protection Phase Sequence Relay
- Model Name: Zahra RST-25
- The electronic phase failure relay RST 25 offers phase failure, phase shift, phase flashing, asymmetric, phase sequence, and also under and over-voltage control
- The RST 25 can be connected as follows in the installation diagram:
- When the relay is connected as in FIG 1, the three yellow LED’s L1, L2, and L3 light up when the power supply A1 phase L, the A2 Neutral, and the three phases “L1”, “L2” and “L3” are properly connected.
- If there is no under of over-voltage, phase failure of phase sequence, the green LED lights up, (terminals 11 and 14 are closed) and the relay is ready for operation.
