TRIP & RECLOSE
Autoreclose following trip
HOT LINE LOCKOUT
Recloser locked out following trip, due to hot line working active
TRIP & LOCKOUT
Recloser locked out following trip
LINE CHECK TRIP
Trip due to switch onto fault
Auto-reclose
SA TRIP
External trip
General Alarms
(user defined text tag)
A user-defined text tag can be programmed, e.g.’ BUCHHOLZ
TRIP ‘. Multiple Alarms are concatenated with ‘ + ‘ symbols
Example
‘12/05/04 17:25:51.2525 G1 PHASE A LS IDMTL <HS1> HS2 IA = 12.32xIn, PHASE B LS IDMTL HS1 HS2 IB = 12.23xIn, PHASE C LS
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:
