3 Total Harmonic Current Non-Dimming Applications When selecting a ballast for a lighting application, the Total Harmonic Current (THC) rating of the ballast is more significant than Total Harmonic Distortion (THD). This is because the absolute value of harmonic current, not the percentage, affects the electrical power distribution system. As can been seen in the table below, the THC rating of our Standard -lamp electronic T8 lamp ballast (REL-P-SC) is well below that of both the conventional (RQM-S40-TP) and energy-saving magnetic T lamp ballasts (R-S40-TP) it replaces. Moreover, the THC rating of our Centium electronic ballast is even lower. Dimming Applications Mark 7 0-0V and ROVR Traditional low voltage controlled ballasts and ROVR typically produce less than 0% THD at full light output and less than 0% THD throughout the entire dimming range, but require extra wires for the control circuit. THC is lower than that of the conventional or energy-saving magnetic system. Mark 0 Mark 0 electronic dimming ballasts are controlled by -wire modified powerline phase-cut style line voltage dimmers. Whenever the ballast is dimmed, the input voltage is cut or chopped, causing the THD to increase and the Power Factor to decrease. Mark 0 electronic dimming systems (ballast and controller) have similar THD and Power Factor levels as the conventional lighting systems they replace. Since a much smaller load is required by the Mark 0 electronic dimming system to achieve the same illumination level as a magnetic ballast system (0-0% less), the total input current will be considerably less. As a result, the magnitude of the total harmonic current will be less. For example, a typical Mark 0 electronic ballast and dimmer control might draw a line current of 0.58A at 5% THD at full light output. If the light level is reduced to 5% of the maximum, the input power is decreased to 0.9A at 95% THD. While the THD level may seem high at the 5% maximum light output setting, the total harmonic current is still lower (0.A) than the conventional T magnetic system (0.0A). Moreover, the overall heating effect on the wires and the distribution transformer is not higher than the existing conventional or energy saving T magnetic systems. Conclusions A simple ballast retrofit to electronic ballasts should not cause harmonic problems if none existed before the retrofit. Also, in new fixture applications, total harmonic distortion should not be a concern when specifying electronic ballasts. Finally, it is important to remember that electronic ballasts are not the greatest source of THD in an electrical distribution system. Other electronic devices such as computers, laser printers, and other electronic equipment can draw current with more than 00% THD in some cases.

Morse. The Total Harmonic Current (THC) of a ballast is calculated by the following equation: An approximation of THC may be obtained by simply multiplying the ballast input current by %THD.
