ABB / Two step overvoltage protection (OV2PTOV) _ Setting & highlights _ AB2050

Table of Contents

Overview

The “Two step overvoltage protection (OV2PTOV)” function can be used to detect open line ends, normally then combined with a directional reactive over-power function to supervise the system voltage. When triggered, the function will cause an alarm, switch in reactors, or switch out capacitor banks.

For more detailed information on “Two step overvoltage protection (OV2PTOV)” function, refer to ABB, Relion 670 Series manuals.
