Supervision Series
Relays
|
| Supervision series
relays is a totally new concept in microprocessor
based intelligent protection controllers. Designed
by P&B Engineering, U.K. for L&T, the
relays are engineered to offer a unique
combination of flexible and easy to use
facilities. |
 |
|
The supervision relay is a totally
integrated device designed to provide all
monitoring, protection and control functions
normally provided on a Vacuum or Air Circuit
Breaker or Starter device by numerous separate
components such as Protection relays, meters,
lamps,push button, timers, transducers etc.
|
|
|
The Supervision series
comprises:
|
 |
Motorvision:
|
|
For Protection Monitoring &
Control of LV and distribution voltage contactor
controlled
motors
. |
|
Advanced
Motorvision: |
|
For
Protection, Monitoring and Control including built in
trip circuit supervision of
LV and
distribution voltage, contactor or circuit breaker
controlled motors. |
|
Feedervision: |
|
For
Protection, Monitoring and Control of LV and
distribution voltage, Air Circuit Breakers and fused
contactors with selectable four stage protection
characteristics and the option of built in Trip
Circuit Supervision. |
|
Advanced
Feedervision:
|
|
A
dedicated system for providing complete protection
including check synchronisation, monitoring and
interlocking for two incomer and bus section systems.
The scheme provides full automatic changeover following
loss of supply and momentary paralleling for
restoration of supplies and to facilitate
maintenance. |
