LINE PARAMETERS

This product requires information about the circuit to which it is applied. This includes line impedance, residual
compensation, and phase rotation sequence. For this reason circuit parameter information must be input using
the LINE PARAMETERS settings. These LINE PARAMETERS settings are used by protection elements as well as by the
fault locator.
4.1 TRIPPING MODE
The Tripping Mode setting selects whether the product should trip single-phase or three-phase when
instantaneous protection elements detect single-phase faults.
Selecting 1 and 3 Pole means that the product will only trip the affected phase for a single-phase fault. For
faults involving more than one phase the product will always trip all three phases.
Selecting 3 Pole means that the product will always trip all three phases.
For products controlling more than one circuit breaker, the tripping mode is independent for each circuit breaker.
The product features an autorecloser that can be used for single-phase autoreclose. In that case, if a single-phase
fault evolves into a multi-phase fault during the autoreclose cycle, the product will switch to three-phase tripping.
