Arc protection with dedicated HSO
Two three-phase overvoltage protection stages PHPTOV offer protection against
abnormal overvoltage conditions that arise due to load rejection or transient surges in
the network or when a generator is running but not connected to a system due to a fault
with AVR. Similarly, two three-phase undervoltage protection stages PHPTUV offer
protection against undervoltage conditions or are used as a backup against
underimpedance protection.
