ST-DUTY Command
Purpose: Read/Set Transformer Duty where mode = 0/1/2 (disable/I*t/I^2*t)
Syntax: ST-DUTY[={mode},{dmax},{ct ckt#},{BLKTXFMR logic}]
Comments: Password Access Privilege G or Privilege S required to change settings. CT# = 1 or 2.
ST-DUTY Command Examples:
Example 1. Enable transformer monitoring on CT 2 with duty calculated as
∑
I*t
, DMAX = 300
operations @ 20 kA with a 100 ms fault clearing time. Block accumulation of duty when
IN5 is energized.
