Introduction

Analog input channels must be configured and set properly in order to get correct measurement
results and correct protection operations. For power measuring and all directional and differential
functions the directions of the input currents must be defined in order to reflect the way the
current transformers are installed/connected in the field ( primary and secondary connections ).
Measuring and protection algorithms in the IED use primary system quantities. Setting values are
in primary quantities as well and it is important to set the data about the connected current and
voltage transformers properly.
A reference
phase angle will always be fixed to zero degrees and all other angle information will be shown in
relation to this analog input. During testing and commissioning of the IED the reference channel
can be changed to facilitate testing and service values reading.

Setting of the phase reference channel

All phase angles are calculated in relation to a defined reference. An appropriate analog input
channel is selected and used as phase reference. The parameter
channel that is used as phase angle reference.

Analog inputs

PhaseAngleRef can be defined to facilitate service values reading. This analog channels
The availability of VT inputs depends on the ordered transformer input module
(TRM) type.
The available setting parameters related to analog inputs are depending on the
actual hardware (TRM) and the logic configuration made in PCM600.
If a second TRM is used, at least one TRM channel must be configured to get the
service values. However, the MU physical channel must be configured to get service
values from that channel.
