BAND PASS FILTER
Q. What does the band pass filter do?
A. The band pass filter blocks power spikes, surges and voltage transients significantly above or below the 60-cycle signal frequency. It blocks harmonic distortion to improve the flow of electricity to the inductive load. This causes the motor to run smoother, quieter and with lower resistance. This reduces motor frame temperature.
Q. Based on the components in the STEMS unit, what and how does each component perform its duties?
A. TVSS components act to remove transient voltages and filter capacitors act to improve Total Harmonic Disturbances, thus further conditioning the AC waveform. This has an effect of helping improve service life of equipment. The effect on motors is that (motors are moveable transformers), they are affected by the rise in current and frequency and generate a variance in the 60Hz waveform. The cumulative effect imposed upon contacts, coils, and semi-conductors by numerous disruptive surges, including harmonics, causes efficiency losses on the motors, which in turn will substantially increase power consumption as the motor compensates to meet demand. As pitting and corrosion occur, there is a rise in the operational temperature of the motor, which increases kilowatt usage and maintenance costs, as well as reduces the life expectancy of the motors and ballast.
MOV (metal oxide varistor), provides a perfect ground, removing high voltage and switching transient voltages.
