XLimHyst : Hysteresis value in % of range and is common for all limits.
All phase angles are presented in relation to defined reference channel. The parameter
PhaseAngleRef defines the reference, see section "".
Calibration curves
It is possible to calibrate the functions (CVMMXN, CMMXU, VMMXU and VNMMXU) to get class
0.5 presentations of currents, voltages and powers. This is accomplished by amplitude and
angle compensation at 5, 30 and 100% of rated current and voltage. The compensation curve
will have the characteristic for amplitude and angle compensation of currents as shown in
figure 186
curve for calculation of factors. The factors will then be used for all related channels.

Setting examples

Three setting examples, in connection to Measurement function (CVMMXN), are provided:
• Measurement function (CVMMXN) application for a OHL
• Measurement function (CVMMXN) application on the secondary side of a transformer
• Measurement function (CVMMXN) application for a generator
For each of them detail explanation and final list of selected setting parameters values will be
provided.

(example). The first phase will be used as reference channel and compared with the
The available measured values of an IED are depending on the actual hardware
(TRM) and the logic configuration made in PCM600.
