These capacitors are available in ratings up to 150kV and can be connected at the primary side of the transformer. This means smaller currents need to be compensated for the same amount of reactive power. Capacitors connected to medium voltage operate on the same principles as low voltage capacitors.
The voltage at which the capacitors are applied can vary +5% or even up to +10%. Voltage less than nominal is not a concern for as the lower voltage will result in lower capacitor current. Harmonics can create additional current flow in the capacitors any where from +20% to +35% of the rated current.
The medium voltage power capacitors comply with most national and international capacitor standards. The 3-phases capacitors HVCB 25 kVAR to 300 kVAR externally fused and QYLP 50 to 400 kVAR internally fused designs are available. High voltage single phase units complete with 1 or 2 bushings are also available.
Capacitors connected to medium voltage are often applied atcentral reactive power compensation. This is an appropriate solution if large numbers of loads, or dispersed loads, are present at the plant. Furthermore, medium voltage compensation is available for higher reactive power compensation than is the case for low voltage.
