IC=0.78xIn, EARTH FAULT LS IDMTL IE=0.27xIn', BUCHHOLZ TRIP
This specifies the date and time of the trip and that settings group 1 was active at the time of trip. On phase A the
lowset, delayed characteristic, and highsets 1 and 2 were picked up. Phase A highset 1 issued the trip/fault
trigger. Phase A current was 12.32 xIn. On phase B the lowset, delayed characteristic, highset 1 and highset 2
were picked up with a current of 12.23 xIn. On phase C the lowset element was picked up with a current of 0.78
xIn. The earth-fault lowset and delayed characteristic elements were picked up with a current of 0.27 xIn, and a
General alarm 'BUCHHOLZ TRIP' was raised. Basically a Phase A to B fault with some Earth fault component,
Phase C unfaulted.

2.13.3 Waveform (Disturbance) Records

Waveform Record storage is a digital graphical record of analogue current (and for Argus 2 type II voltage) inputs,
status inputs and relay outputs.
Each record is one second in length and is triggered from a protection element operating or from a status input as
designated in the Data Storage:Waveform Trig setting. This allows the user to specify one or more trigger methods:

Forward and reverse direction. User-defined text tags can be
programmed for each direction, e.g. LINE, BUS, FEEDER,
TRANSFORMER, etc.
