The function registers its operation into the last twelve (12) time-stamped registers. The register of the
function records the ON event process data for ACTIVATED, BLOCKED, etc. The table below
presents the structure of the function's register content.

5.3.8 Overvoltage protection (U>; 59)
The overvoltage function is used for instant and time-delayed overvoltage protection. Each relay with a
voltage protection module has four (4) available stages of the function (U>, U>>, U>>>, U>>>>). The
function constantly measures phase voltage magnitudes or line-to-line magnitudes. Overvoltage
protection is based on line-to-line RMS voltage or to line-to-neutral RMS voltage (as the user selects). If
the protection is based on line-to-line voltage, overvoltage protection is not affected by earth faults in
isolated or compensated networks. The blocking signal and the setting group selection control the
operating characteristics of the function during normal operation, i.e. the user or user-defined logic can
change function parameters while the function is running.
The outputs of the function are the START, TRIP and BLOCKED signals. The overvoltage function
uses a total of eight (8) separate setting groups which can be selected from one common source.
The function can operate on instant or time-delayed mode. In time-delayed mode the operation can be
selected between definite time (DT) mode and inverse definite minimum time (IDMT).
The operational logic consists of the following:
• input magnitude selection
• input magnitude processing
• threshold comparator
• block signal check
• time delay characteristics
• output processing.
