Complete Control & Total Protection
ETA's range of Protection Relay Panels, Control Panels
and Control Desks are specially engineered and custom
built to cater to the specific needs of the utilities
and large industrial undertakings for medium and high
voltage protection, control and monitoring applications.
These panels are specifically designed for the local
environment and ambient conditions.

Protection Relay Panels - TYPE EM RP
Separate Protection
Relay Panels for high voltage (upto 220kV) and medium
voltage (upto 33kV) are usually constructed as
individual panels, one for each bay of switchgear. These
panels have hinged doors in the front with a glass
window. The protection relays are mounted on a 19" rack,
and are accessible after opening the front door. A
hinged rear door provides access to the terminals and
other components. |

Control Panels
Control Panels for the high voltage and medium voltage
switchgear are generally individual panels, one for each
bay of switchgear. Sometimes due to space constraints,
the control requirements of more than one bay of
switchgear are housed in one panel. The control panel
has a fixed front cover with a mimic diagram of the
switchgear and all operational / are installed inside
and will be accessible on opening the hinged rear door.
Combined Control and Relay Panels
For
medium voltage schemes where the protection relays are
limited, it is sometimes preferable to have a single
panel to house the protection as well as the control
equipment. |
|
|
| |
Such panels have
a fixed front cover where the protection relays and other
control components would be flush mounted.
Alternatively, the protection relay portion of the C&R panel
could be provided with a hinged door while the control
portion would be situated on the fixed front cover. |

LCCs and Busbar Protection Panels
Local
control cubicles for the high voltage GIS (Gas Insulated
Switchgear) and Busbar protection panels are custom
built according to operational requirements.

Construction
|
|
| |
|
|
| |
The protection relay and control panels are made of
electro-galvanized steel with a powder-coated finish. These
panels have an external paint finish of silicon grey, RAL
7032 and an internal finish of white, RAL 9003. The panels
are provided with thermostatically / hydrostatically
controlled anti condensation heaters to prevent moisture
built-up inside the cubicle Internal cubicle illumination
with door operated switch is provided as standard. The panel
design permits the cubicles to be joined together to form a
complete suite of panels. Partition, plates are provided
between individual cubicles. These plates also have the
facility for inter bus wiring and continuity of the Earth
bar. |

Components |
|
| |
|
|
| |
All control
components used in the C&R Panels are from well-known
European / American manufacturers. Protection relays of any
make can be offered. |
|
| |
|
|
| |
Tests |
|
| |
|
|
| |
All panels
undergo stringent tests as per IEC 60439 standards. Complete
functional tests of the wired up system are also carried out
to prove the design and tripping logic .. |
