2.6.6 Voltage and Synchronism Check Elements OVL, UVL, OVB, UVB, and SYN

The voltage check and synchronism check elements are used for autoreclose.

The output of the voltage check element is used to check whether the line and busbar are dead or
live. The voltage check element has undervoltage detectors UVL and UVB, and overvoltage
detectors OVL and OVB for the line voltage and busbar voltage check. The under voltage detector
checks that the line or busbar is dead while the overvoltage detector checks that it is live. These
detectors function in the same manner as other level detectors described later.

Figure 2.6.6.1 shows the characteristics of the synchronism check element used for the autoreclose
if the line and busbar are live.

The synchronism check element operates if both the voltage difference and phase angle difference
are within their setting values.
