Apfc Panel Circuit Diagram

We can share the apfc panel circuit diagram upon request.

Apfc panel circuit diagram. Note that apfc panel can maintain the power factor on l t side of transformer and it is necessary to provide fix compensation for power transformer refer fig no 1 5. Incomer circuit breaker mccb shall be mounted in a separate compartment and metering compartment along with apfc relay etc shall be separate. To measure reactive power at the power factor relay especially it must be ensured that the vectors of voltage and current are shifted by 90. Lm358 is used as a comparator in this circuit.

To correct power factor first we need to find the current power factor. This gives you more reasons to consider the panels. Power factor can be explained as ratio of active power to apparent power and it is a key factor in measuring electrical consumption. Furthermore it has special switching capacitors that help in the minimization of the transients when making any changes to the system.

Automatic power factor control apfc panels. Free download edraw electrical diagram maker. In order to measure electrical power the relay needs to receive the line voltage and current from a current transformer ct installed close to the metering point if possible. Similarly voltage transformer is used to get current wave form and fed this wave to lm358 comparator.

Fabricated from sheet steel shall be crca of minimum 2 0 mm thickness. Refer fig no 3 fig m. It can be find by taking tangent of ratio of time between zero crossing of current and voltage waveforms and two successive zero crossing of voltage waveform. The 440v apfc panel shall be metal clad indoor type floor mounted in non drawout execution.

In above circuit diagram of automatic power factor controller current transformer is used to get current wave form from of load current and current transformer also step down ac current. In case there is no transformer in the installation then the c t for sensing power factor should be provided at the incoming of main switch of the plant. Https bit ly 30qgwfe why we use apfc panel. Circuit diagram of pf relay.

Everyone knows that how costly electricity has become in present time. I hope you will find it very useful because i have already spent two days to prepare this article. I think all of those who have sent messages and mails about the topic will never ask again if they follow these simple methods to calculate the proper size of capacitor bank in kvar and micro farads for power factor correction and improvement in both. Its modular design helps in ensuring you have an easy time in maintaining your system.

With a very important tutorial. Apfc or automatic power factor control panels are mainly used for the improvement of power factor. Pic 16f877a microcontroller is the heart of this automatic power factor controller it find displays and controls the power factor.
