Figure 23:
Arc protection with dedicated HSO
Two overvoltage and undervoltage protection stages PHPTOV and PHPTUV each
offer protection against abnormal phase voltage conditions. Positive-sequence
undervoltage PSPTUV and negative-sequence overvoltage NSPTOV protection
functions enable voltage-based unbalance protection. A failure in the voltage
measuring circuit is detected by the fuse failure function. The activation is connected
to block the undervoltage protection functions and the voltage-based unbalance
protection functions to avoid faulty tripping.
