#automatic correction

The automatic power factor correction unit oversees the total consumption of energy & automatically boosts the power factor value. Such automatic switching of the capacitors allows the intended amount of PF correction & avoids the PF overcorrection. APFC panels will enable the system to restore its power factor value closer to unity so that all the economic operations can be held smoothly. 

Power correction allows the enhanced load-carrying ability, strengthened voltages & decreased the power system losses. The APFC panel device evaluates the total consumption of reactive power through a network’s inductive load. After accessing this, it takes the capacitance from the capacitor bank to reimburse for the lagging power factor.

Most power supply utilities ask the customers to pay an extra amount for the kW - baseload and utmost demand tariff. In scientific terms, we measure this maximum demand tariff in kVA. It essentially says that once the passive power factor correction improves the PF value, the kVA value of the installation gets decreased. 

Due to this, it lowers the maximum demand tariff leading to minimizing power expenses. Power matrix, a leading harmonic filter manufacturer, uses Power factor correction capacitors since it's effective for economic design. Microcontrollers generally determine the power factor value & then capacitors are inaugurated into the network.  

Is automatic power factor correction necessary?

If the power factor value of your equipment comes to -0.4, then it demonstrates that only 40% of power is efficiently utilized, and then the remaining 60% is wasted. The power that gets destroyed from the total supplied power to businesses is known as the reactive power. 

When the current is raised in the system, the heat also gets triggered, influencing the lifespan & durability of an electrical network. It increases the installation cost and badly affects the plant growth. The automatic power factor correction is necessary to save yourself from heavy penalties. You might be spending money on reactive power that's of no use in strengthening the device's power. 

Customers are supposed to retain a minimum power factor value based on the area they live in, according to the network regulatory guidelines. Else they have to pay the penalty. These penalties are often charged in addition to the consumption charge whenever the power factor value comes below the determined value. 

Equipment or any load having a  poor power factor pulls out more current than a load. It leads to a negative impact on the electricity distribution network. Active harmonic filters, when combined with passive harmonic filters, form a hybrid harmonic filter. The Hybrid PQ filters are well known to improve the poor power factor value. 

If you forget to rectify the power factor value, the current flow will surplus in the source, declining the magnetic field. Thus, due to this, the overall capability of elements present in the transmission line gets restricted. The power source cable must fulfill the supply of only load current as the capacitor provides the magnetizing current. 

Moreover, the power factor correction capacitor helps to achieve minimum monthly power consumption & charges. It allows you to curtail your electricity bill expenses by a considerable amount. Power factor correction has a payback period of 1 to 3 years. Thus, the equipment's life expectancy and the possible savings make it a beneficial investment. 

Poor power factor leads to plunged voltage & power loss. It causes system downfall & overheating. The power factor correction capacitor decreases the trash reactive power element from the total consumption. It leads to substantial monetary savings from a business point of view. It does so by helping you to lessen the electrical demand of your equipment, which leads to no requirement for costly upgrades.
