InrushRatio Ratio of 2nd. harmonic current content to fundamental current above which an inrush condition is detected. InrushTime Time during which the inrush detection function is active following initial energisation or an external fault. a1 Amplitude compensation factor for winding 1. s1 Circuit of winding 1 (primary). Settings provided:
Y: Y-connected
D: delta-connected CurrentInp1 defines the current input channel for winding 1. The first channel (R phase) of three phases must be specified. a2 Amplitude compensation factor for winding 2. s2 Group of connection for winding 2. Settings provided: All usual groups of connection with
designation of the circuit (y = star, d = delta, z = zigzag)
phase-angle adjustment of the winding 2 voltage in relation to the winding 1 voltage in multiples of 30°. CurrentInp2 defines the current input channel for winding 2. The first channel (R phase) of three phases must be specified. a3 Amplitude compensation factor for winding 3

s3 Group of connection for winding 3. Settings provided: All usual groups of connection with
designation of the circuit (y = star, d = delta, z = zigzag)
phase-angle adjustment of the winding 3 voltage in relation to the winding 1 voltage in multiples of 30°.

CurrentInp3

 defines the current input channel for winding 3. The first channel (R phase) of the two groups of three phases must be specified. The protection operates in a two-winding mode, if a third I/P is not selected. BlockInp Binary address used as blocking input. (F
FALSE, T
TRUE, binary input or output of a protection function). InrushInp determines whether the inrush restraint is activated, even though the transformer is already energised. This enables, for example, the inush current resulting from energising a parallel transformer to be detected and compensated. (F
FALSE, T
TRUE, binary input or output of a protection function) The I/P must be energised for the entire expected duration of the inrush current. HighSetInp determines with the normal or increased basic setting g is used. (F
FALSE, T
TRUE, binary input or output of a protection function). Trip Output for signalling tripping (signal address) ER means event recorder. Note: The differential protection function does not have a pick-up signal. Every time it trips, the signal ‘GenStart’ is set together with ‘Trip’, providing the tripping command is configured to be recorded as an event. Trip-R corresponds to Trip, but indicates that tripping was initiated by R phase. Trip-S corresponds to Trip, but indicates that tripping was initiated by S phase. Trip-T corresponds to Trip, but indicates that tripping was initiated by T phase. RE. 216 1MDU
