Electric heater power factor
WebSep 22, 2024 · The system’s power factor shouldn't fall below a certain level because if it does so reactive power charges will occur. In most cases, most power suppliers will define a charge anytime the power factor falls below 0.95. A perfect power factor is at 1.0 and this can, in most cases, be achieved by an ideal system.
