Power Distribution is a system, consisting of a Main Distribution Board (MDB/LT), Sub Main Distribution Boards (SMDBs) and Final Distribution Boards, by which the electrical energy is transmitted via branches to reach the exact end user.
An MDB is a panel or enclosure that houses the fuses, circuit breakers and ground leakage protection units where the electrical energy, which is used to distribute electrical power to numerous individual circuits or consumer points, is taken in from the transformer or an upstream panel.
An MDB typically has a single or multiple incoming power sources and includes main circuit breakers and residual current or earth leakage protection devices. A MDB is comprised of a free standing enclosure, a bus bar system, MCCB's, metering and support equipment’s and required current transformers. Panels are assembled in a systematic manner such as incomer section and outgoing section.
Capacitor Banks improve the power factor by adding capacitive reactance in steps as per the power factor requirement. Power factor controller constantly monitors the load (and power factor) of the system on LV Panel and switch on/ off the capacitor steps to maintain the system power factor to the set value. It provides optimum power factor improvement to compensate for lagging Vars in the system, seen as a clean and reliable solution to providing quality power to the distribution network and to economize the electricity charge to customer/consumer.
The MDB then feeds SMDBs, which is installed generally at the point where a large distribution cable terminates and several smaller sub-circuits start. These are the switchboards that although similar construction, are larger than a final distribution board circuit. The boards are installed midway through the power distribution system, at the point in a large distribution cable ends, and several smaller starting sub-circuits.
The Sub-Main Distribution Boards feeds the Final Distribution Board, which then feeds electrical energy to the end user.
Motor control centers are simply physical groupings of combination starters in one assembly. A combination starter is a single enclosure containing the motor starter, fuses or circuit breaker, and a device for disconnecting power. Other devices associated with the motor, such as pushbuttons and indicator lights may also be included. These usually comprise of incoming Air Circuit Breakers, main horizontal and vertical bus bars, outgoing starter modules with MCCB / Switch Fuse Unit, overload relays, contractors, etc. with adequate space for connection of cable and are easily extendable on either side and have excellent short circuit withstand performance of Bus Bars comprised of bolted / riveted modular construction.
Feeder pillar or Lighting Control Panels are manufactured in galvanized/electro galvanized steel sheets or aluminum sheets. Single wall and Double wall constructions are available on request and are available in 4 / 6/ 8 way distribution. These include instrument panel with voltmeters, ammeters, service fuses and selector switches. The built, structure and designs are suitable to all kinds of lighting applications.
Synchronizing panel will operate on an automatic mains failure system, so that when the main supply is interrupted on one or all phases (after an adjustable delay period) the generator sets will start-up together. After an initial warm-up period (adjustable) the generators will synchronize with each other by means of motorized circuit breakers or contactors onto a common busbar. Next, the motorized change-over switch will be closed and the load will be connected to the main distribution box. The load share units continuously monitor the load and during low demand periods one or two generators will be shut down to save on fuel consumption. As demand rises again the second generator and third generator will be restarted, synchronized and reconnected to the load. When the AMF control unit detects that the main supply has been restored an adjustable observation period is activated before the main supply is reconnected. A cool down period will then follow, after which the generator sets will be shut down.
