LV Power Factor Improvement Plant |
These panels are used for power factor correction and manufactured
as indoor units with fixed or automatic capacitor
switching. The panel is designed to align and couple with the
LT distribution panels. If requested, reactors can be used to
eliminate unwanted harmonics. The PFI panel is of self-ventilating
design.
The components used are highly robust and reliable.
- Microprocessor based control unit with built in PF meter,
user–friendly programmable parameters (sequence, C/K,
switching delay etc.).
- Adequately rated air break contractors backed by HRC
fuses.
- Self-healing, internally protected, dry type capacitors,
having very low losses and rated for 1.1x Un and 1.3xIn.

Motor Control Centre (MCC) |
These panels are manufactured at various power levels as indoor
units. Draw–out units vary in size and power level. Interlocks,
covers, etc. are provided to prevent incorrect or unsafe
operation and to prevent access to live parts. The bus bars are
at the top of the assembly and are contained within segregated
chambers. The riser bars also run within a segregated
chamber, down each rack section to feed individual compartment
through an automatic shutter system. These units
are used at command and control system. Repair and maintenance
can be carried out on a withdraw-able unit without
interrupting power to the other units. |

We at PEL develop and fabricate made-to measure low voltage
Bus Duct systems is air insulated, non–segregated construction.
Our Bus Ducts are designed to meet the required
voltage, ampere and fault level ratings.
Copper bus bars are sized in accordance with the specified
ratings to operate within IEC temperature rise limits. Joints
are tin-plated. Provision for the bus expansion is furnished
as required by the configuration and length of each system.
Flexible connections are provided at the transformer end to
absorb the vibrations. Enclosure up to 3000A rating is made of
sheet steel while above 3000A (up to 6000A), non-magnetic
aluminum enclosures are used to eliminated hysteresis losses.
The enclosure is of self-ventilating design. |
