Figure 18: 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 IED.
3.10.1.3 Dual single-pole high-speed power outputs HSO1, HSO2 and HSO3
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 or electromechanical output that is rated as a power output.
The outputs are normally used in applications that require fast IED 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 IED 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.
