Global compensation Where a load is continuous and stable, global compensation can be applied Principle The capacitor bank is connected to the busbars of the main LV distribution board for the installation, and remains in service during the period of normal load. Advantages The global type of compensation: Reactive current still flows in all conductors of cables leaving (i.e. downstream of) the ma...

What is Power Factor? Power factor is a measure of how effectively you are using electricity. Various types of power are at work to provide us with electrical energy. Here is what each one is doing. Working Power – the “true” or “real” power used in all electrical appliances to perform the work of heating, lighting, motion, etc. We express this as kW or kilowatts. Common types of resistive loads a...

STATCOM STATCOM (Static Synchronous Compensator)continuously provides variable reactive power in response to voltage variations, supporting the stability of the grid. STATCOM operates according to voltage source converter (VSC) principles, combining unique PWM (pulse width modulation) with millisecond switching. STATCOM functions with a very limited need for harmonic filters, contributing to a sma...

STATCOM A static synchronous compensator, known as a STATCOM, is another device used to regulate the power factor in medium to high voltage applications. They operate on roughly the same principles as a synchronous compensator, however, use a voltage source converter as opposed to a rotating machine to provide dynamic Power Factor Correction. STATCOMs use IGBT switching te...
