Figure 24:
Double-pole power outputs PO3 and PO4 with trip circuit supervision
Power outputs PO3 and PO4 are included in the power supply module located in slot X100
of the protection relay.
3.12.1.3
Dual single-pole high-speed power outputs HSO1, HSO2 and HSO3 in
BIO0007
HSO1, HSO2 and HSO3 are dual parallel connected, single-pole, normally open/form A
high-speed power outputs. The high-speed power output is a hybrid discrete and
electromechanical output that is rated as a power output.
The outputs are normally used in applications that require fast relay output contact
activation time to achieve fast opening of a breaker, such as, arc-protection or breaker
failure protection, where fast operation is required either to minimize fault effects to the
equipment or to avoid a fault to expand to a larger area. With the high-speed outputs, the
total time from the application to the relay output contact activation is 5...6 ms shorter than
when using output contacts with conventional mechanical output relays. The high-speed
power outputs have a continuous rating of 6 A.
