The IED reports all valid measuring types depending on connected signals.
Upper limit for measured currents, active/reactive-power is 2.4 times rated value.
Upper limit for measured voltages and frequency is 1.2 times rated value.
The upper limit is the maximum value that can be encoded into the ASDU
(Application Service Data Unit). Any value higher than this value will be tagged as
OVERFLOW. The factors 1.2 and 2.4 are taken from the 103 standard and require
that a rated value to use as base exists, and then use 1.2 or 2.4 times <rated> as
maxVal. You can use 2.4 times rated as maxVal, but as there is no way to propagate
value to client, the use of a scale factor on <rated> does not make much difference.
You can configure client:client-scaled-max ::= 1.2 * <rated> or
client-scaled-max ::= 1.0 * <maxVal>
If the client has a hard-coded gain of 1.2 * <rated> then client-scaled-
max ::= 1.2 times <maxVal>/1.2
Resolution is <maxVal> / 4095 and hence the lowest possible maxVal yields the
best accuracy.
