4.6.Setting command for Relay's Trigger time function (pre-programmed functions)
!Attention: functions based on buffers do not allow to program interharmonics!
Relay's Trigger time function is based on fast ramp protocol with additional commands.
Relay's trigger time function according to
Calpro300 TS user manual
(chapter 3.3) consists of 3 general
states (each state is a one buffer):
1.
Prefault state – first buffer, consists of prefault settings,
2.
Fault state – second buffer, consists of fault settings and TIMERTRIGGER_ command,
3.
Postfault state – third buffer, consist of postfault settings (standby or prefault state).
Function
Start trigger's time measure
Command
TIMERTRIGGER_[CR][LF]
Description
Start trigger's time measure (timers starts measure the time from 0ms).
!!!use this command only in buffers which will be measured the time or to use the jump to
another buffer (RELAYTESTPOSTSETTINGS_ command)
