LVMDP & Capacitor Bank The Low Voltage Main Distribution Panel (LVMDP), functions as the panel to receive power from 20 kV – 380 V transformer and distributes this power further to the Low Voltage Sub Distribution Panel (LVSDP) Capacitor Bank, in other for motor or other electrical appliances to run, they require consumptive power (rated in kW) as well as reactive power (rated in kVAR). Without use of a Capacitor Bank, the supply (PLN or Gensets) must provide for both powers.
