The KAVR is a compact, multi-shot auto-reclose relay with built-in synchronism check features.

It is a compact and simple solution for single or 3-phase reclosing as the first shot. Applicable to all power systems, these relays are user-friendly and enhanced with flexible operating logic.

Single or 3-phase auto-reclosing capacity

KAVR is a multi-shot auto-reclose relay with integral check synchronising for application to feeders switched by a single circuit breaker. Part of the K relay range, it can be integrated into an overall protection and control system via its integral serial communications facility.The KAVR 130 can be applied for single or 3-phase reclosing, while the KAVR 100 is only for three-phase reclosing. Appropriate for all power systems from distribution to transmission voltages, KAVR relays can be simply configured for both automatic reclosing and manual reclosing interlock.

User-friendly, compact and flexible

Compact, numeric KAVR relays benefit from optimal design. They are equipped with a user-friendly interface and flexible operating logic.

The KAVS is a stand-alone check-synchronising relay for application to feeders on transmission, sub-transmission and distribution systems.KAVS is a stand-alone synchronism check relay that can be applied on all power systems from distribution to transmission voltages. It is user-friendly and flexible in its operating logic.

Integral serial communications and check-synchronisation

Part of the K relay range, KAVS is designed for use in all power systems from distribution to transmission voltages. It can be integrated into an overall protection and control system via its integral serial communications facility.KAVS checks that the voltage, phase angle and frequency on either side of an open circuit breaker are such that it is safe to close.KAVS provides the check synchronising or dead line/bus interlocks required for some auto-reclose applications, as well as split system detection. It also checks synchronising interlocks for manual reconnection following a system split.
