1. UVR - Under Voltage Relay
Off/Alarm/DO is available when under voltage occurs to one of the 3 phases.
1) Pickup standard voltage setting (UV_pickup): 80 ~ OVR_PickUp
Note1
) V (Step: 1V)
2) Delay Time (tuvp): 1.2 ~ 40 sec (Step : 0.1 sec)
3) Relay error: Pickup value 5%, Operating time 0.1sec.
4) Remark: From 3P Voltage, Max. voltage operate at above 60V.
2. OVR - OVER Voltage Relay
Off/Alarm/DO is available when under voltage occurs to one of the 3 phases.
1) Pickup standard voltage setting (OV_pickup): UV_pickup
Note2
) ~ 900V (Step: 1V)
2) Pickup time delay setting (tovp): 1.2 ~ 40 sec (Step: 0.1 sec)
3) Relay error: Pickup value 5%, operating time 0.1 sec.
3. rPower - Reverse Power Protection
Off/Alarm/DO setting available when total active power of 3P flows reverse above the setting.
1) Pickup setting: 10 ~ 500kW (Step: 1kW)
2) Pickup time delay setting: 1.2 ~ 40 sec (Step: 0.1 sec)
3) relay error: Pickup value 10%, Operating time 0.1sec.
4) Calculating formula and Remark: absolute power phase angle difference
(Voltage phase difference- Current phase difference) 0 ~ 60°
Note 1) OVR_PickUp - OVR Pickup setting voltage
2) UV_PickUp - UVR Pickup setting voltage
