Various measuring and monitoring relays are available for the purpose of monitoring electrical quantities. In addition to overvoltage, undervoltage, frequency, unbalance, phase sequence, phase failure and loop monitoring, special solutions for specific applications are also possible: extended temperature ranges, sector-specific standards, compact design, country-specific profiles.
