5.3.9 Undervoltage protection (U<; 27)

The undervoltage function is used for instant and time-delayed undervoltage protection. Each

device 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 voltage

magnitudes. Undervoltage protection is based on line-to-line RMS voltage or to line-to-line RMS

voltage (as the user selects). If the protection is based on line-to-line voltage, undervoltage protection

is not affected by earth faults in isolated or compensated networks. Undervoltage protection has two

blocking stages: internal blocking (based on voltage measurement and low voltage), or external

blocking (e.g. during voltage transformer fuse failure). 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 undervoltage 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
• two block signal check
• time delay characteristics
• output processing.

The inputs for the function are the following:

• operating mode selections
• setting parameters
• digital inputs and logic signals
• measured and pre-processed voltage magnitudes.

The function outputs the START, TRIP and BLOCKED signals which can be used for direct I/O

controlling and user logic programming. The function generates general time-stamped ON/OFF events

to the common event buffer from each of the three (3) output signals. In the instant operating mode the

function outputs START and TRIP events simultaneously with an equivalent time stamp. The time stamp

resolution is 1 ms. The function also a resettable cumulative counter for the START, TRIP and

BLOCKED events.

The following figure presents a simplified function block diagram of the undervoltage function.
