7. Application
The following chapters illustrate the versatile functions of the
overcurrent and earth-fault protection relays VAMP 50 and
VAMP51 as well feeder and motor protection relay VAMP52 in
different protection applications
The relays can be used for line/feeder protection of medium
voltage networks with grounded, low-resistance grounded,
isolated or a compensated neutral point. The relays have all the
required functions to be applied as a backup relay in high
voltage networks or to a transformer differential relay. In
addition VAMP52 includes all the required functions to be
applied as motor protection relay for rotating machines in
industrial protection applications.
The relays provide circuit-breaker control functionality,
additional primary switching devices (earthing switches and
disconnector switches) can also be controlled from the relay
HMI or the control or SCADA/automation system.
Programmable logic functionality is also implemented in the
relay for various applications e.g interlockings schemes. For
details about the functionality in the relays see chapter 2.2 List
of protection functions.
