can be modified.
Type:
different channel type such as different voltage and current, has different
conversion ratio, further gets different testing value.
Angle:
Some options such as sequence, power and phase-check will affect the SMV.
The three-phase current/ voltage should be distinguished to get a proper calculation and
analysis result.
Primary/ Seondary: According to the IEDs’ settings, primary or secondary could be
transmitted in SMV messages. If the primary/ secondary is changed, the equal ratio will
be changed accordingly. Besides, if the value is set incorrectly, the RMS will be not
correct. In this regards, it is suggested to check the real ratio of the CT and make the
testings.
