What is reactive power compensation?

Reactive power compensation is controlled with the N-6 high performance reactive power controller. Power factor correction by means of conventional capacitor banks is not possible in systems affected by harmonics. This is because the harmonic currents are amplified in the parallel resonant circuit formed by the capacitor and the network.

What are automatic capacitor banks?

Automatic capacitor banks are used for centralized power factor correction at the main and sub distribution boards. Power factor correction means that reactive power charges imposed by electricity utilities can be avoided.

What is low (LV) reactive power compensation & harmonic filtering?

Low (LV) reactive power compensation and harmonic filtering solutions help customers to improve the performance of installations through energy savings and better power quality, enabling end users to save money and reduce the environmental impact of their operations.

What is a DW-series automatic capacitor bank?

GE's DW-series automatic capacitor banks with blocking reactors are intended for power factor correction in systems where harmonic distortion is present. The new modular and compact design saves space and is available with options for wall or floor mounting. The DW-series is available in two variants, standard and extendable.

What is a detuned filter capacitor bank?

Wall or floor mounted detuned filter capacitor banks are manufactured for 400 V/50 Hz networks with 141 Hz and 189 Hz tuning frequencies. Other configurations are available to order. Power transmission and distribution systems are designed to operate with sinusoidal voltage and current having a constant frequency.

What happens if capacitance and network inductance resonant?

Capacitor capacitance and network inductances may form a parallel resonant circuit, where harmonic currents may be as much as 20 times the normal level. Should the natural frequency of the resonant circuit match an existing harmonic frequency, the current distortion caused by resonance leads to further voltage distortion.
