APFC is an Active/automatic power factor Correction/Control electrical device which is employed to boost the power factor, whenever required, by switching ON and OFF the desired capacitor bank units automatically. These are stage-based pre-programmable microcontroller with multiple capacitors and can be turned on or off automatically as per requirements by triggering the capacitor banks in multiple stages by directly sensing the reactive load, which works on the principle of VAR sensing and tends to keep the power factor close to unity. #apfc #powerfactor #power #apfcpanel #electricalengineer #knowledge (at Kolkata) https://www.instagram.com/p/CbSZ1Pvp9Wu/?utm_medium=tumblr
