Power Factor Correction and Harmonic Filtering in their own essence complement each other and are both used for achieving optimization of electrical systems. In basics, Power Factor Correction is an approach geared towards optimizing the use of power by improving the phase between voltage phases and current’s, while fighting the harmonic waves that are generated by the non-linear loads is what Harmonics Filtering is all about. Both solutions are essential to overcome and improve energy effectiveness as well as cut down the operational cost and enhance the operational lifespan of electrical devices and equipment. Construction of new directives into the system allows Sinotech Group to adopt wide-range solutions in response to different requirements, so that best results are achieved in client's power systems operability
