16.7.2 Total harmonic distortion detection (TTHD) – indicator W2
Using the total harmonic distortion measurement the 10min average TTHD values of the phase
voltage values are considered.
The characteristic of the indicator W2 for the TTHD measurement is based on:
• Detection of the maximum 10min (standard, but configurable) TTHD value of the voltage
in any phase,
TTHD> TTHD
lim
(+/-8%, value configurable)
16.7.3 Voltage unbalance – indicator W3
Using the voltage unbalance measurement the 10min average voltage values including the
phase angles are considered.
The characteristic of the indicator W3 for the voltage unbalance measurement is based on:
• Voltage unbalance limit (2%, configurable)
• Conformity level K
CP
=95% (configurable), number of 10min values inside the range of
95% over 1 week
• N
3
number of 10min Intervals, which are below the voltage unbalance threshold of 2%
