"KAVR 130 Areva
• KAVR 100
3 phase tripping only
• KAVR 130
Single and 3 phase tripping
Application
The KAVR 100 provides 1, 2, 3 or 4
shot reclosure of a circuit breaker
following a fault on an overhead line.
The first shot can be selected to be either
high speed or delayed three phase
reclosure.
The KAVR 130 is specifically designed
for transmission and sub-transmission
lines where there is a need for singlephase
auto-reclosure. In addition to the
cycles available on the KAVR 100, it
gives the option of high speed singlephase
auto-reclose for the first shot.
The check synchronising function ensures
that the two parts of the system are
sufficiently in synchronism before being
connected together. This function can
also be used with manual switching and
is operable even when the auto-reclose
function is out of service.
Functions
Auto-reclose
The auto-reclose cycle is initiated by the
operation of the associated protective
relay. Flexible scheme logic is provided
to allow the relay to be used for a wide
range of applications.
KAVR 100 and 130 are multi-shot auto-reclose relays with integral check synchronising for application to feeders switched by a single
circuit breaker. They are intended for use on transmission, sub-transmission and distribution systems
As a part of the K range of relays, the KAVR can be integrated into an overall protection and control system by utilising its integral
serial communications facility

"KVGC 202 areva,

The KVGC relay provides regulation of the supply voltage within finite limits by controlling transformer tap changing.

The KVGC 202 relay can be used to maintain a regulated voltage supply to electrical equipment designed to operate within finite limits of its designed rated voltage. Failure to maintain a regulated voltage supply within these defined limits may cause extensive damage. Regulation is achieved by the operation of voltage regulating transformers of various types, the most common being the on-load tap changing transformer which maintains a stable secondary voltage by selecting appropriate tappings on the primary winding."
