The ever-increasing use of power electronics and other solid state devices, which generate harmonic voltages, make the issue of power quality more and more important both for suppliers and users of electrical power. Complex waveforms created by solid-state devices in power system converters, motor controls, etc. feed harmonics into power systems, causing trouble with equipment connected elsewhere in the system.
The solution is higher order harmonic filters consisting of capacitors, inductors and resistors tuned to eliminate specific frequencies. The capacitors and inductors allow the fundamental frequency through and divert the harmonics into the filter resistor where the harmonic currents are dissipated as heat and thus lost from the system.
Post Glover designs, builds and tests their filter resistors in accordance with applicable IEC and IEEE standards to guarantee their performance. With no two installations ever being the same, our experienced engineers develop the proper solution for your particular application and environment. Our low inductance designs are built using all stainless steel elements in corrosion resistant enclosures chosen for your unique specification. Post Glover’s reputation in filter resistors has been built on over 100 years of field performance and independent test facilities, where we’ve proven our engineering and manufacturing prowess to be second to none.
