POWER FACTOR REGULATOR

Dear Robert,

Power factor regulator is an electronic instrument that helps to regulate your supply power at unity power factor. That is, line current to be maintain at unity power factor w.r.t. supply voltage. This reduces the reactive power in the distribution & transmission lines, reducing I2R losses. Maintaining power factor at unity ultimately improves the transmission & distribution eficiency, & saves fuel requirements in the generating power plants.

Dear

First you check your Power Factor of the Plant . May be for inductive load it depend & too on harmonics . It vary from Plant to plant load pattern . If you have fwe resistive load like heating furnace than your PF can be improve side.

For exmpale if any Plant having Power Factor (PF) 0.85PF . If you want to improve by the Power Factor regulator towards 0.9PF . To improve the PF you must having Panel consist of Automatic Power Factor correction Relay (APFC) , Capaitor bank connected . This will work on the Voltage & current feedback to the APFC realy .

In this APFC relay you have to set the power factor want you want correct Like 0.98PF on this set point it will check with you running PF of the Plant and if it is less than your set pointthis realy swicth ON the capacitors as connected in the circuit

If you set the PF "unity" it will not good for generators. These capacitor bank supply the reactive power to Main bus of you Plant . This reactive power compensatation will improve the PF

You can check also the haromics level in your plant if yuou have AC & Dc drive more in machine .
