The building is supplied by a 230 Vrms source. 1. What is the average current (in A rms) drawn by the building? 2. What is the effective impedance of the building? 3. What will be the surcharge (in %) to be imposed on the building? The building occupants are planning to avoid the additional cost by installing a capacitor (to be connected in parallel with the building) for localized reactive power production. The target is to reduce the surcharge to 0%. 4. What is the minimum KVAR the capacitor should produce to meet the target?

![A medium-rise building with inductive loads has an average consumption of 40 kW and 26
KVAR. At the area where the building is located, the electric utility imposes a surcharge (or
additional payment, in %) based on the power factor of the load. The utility uses the table below
to determine the surcharge.
