N.B. : The double arrow ¯ means the event is generated on event
occurrence and another is generated on event disappearance.
On event occurrence, the corresponding bit of the associated
format is set to "1".
On event disappearance, the corresponding bit of the associated
format is set to "0".
CODE DESCRIPTION
F68 Conversion rules for the fault records
In order to obtain phase and residual voltages at primary VT, apply the following
formula :
Range 57 to 130V :
"Read value".* ("primary phase VT" / " Secondary phase VT ") * 1/63
Range 220 to 480V :
"Read value".* 1/17
Conversion formula (fault magnitude in case of a frequency fault):
1000000/ "Read value"
