Automatic testing of positive/negative/zero sequence overcurrent characteristics Overcurrent is used for automatic testing of directional and non-directional overcurrent relays with auto-assessment of the trip time characteristic, the directional boundaries of the current stages, and the pick-up/drop-off ratio. Dierks, Eskom, Republic of South Africa. Title Language Pub. 8. 1.3.3 Time-overcurrent relays A time-overcurrent relay characteristic is generally plotted as a single-line curve. For these tests, the relay outputs are normally disconnected from the remainder of the protection scheme, as it is a test carried out to prove correct relay, rather than scheme, operation.
