Which is the correct definition of THD as put forth in IEEE 1159? THD is the power factor under the condition of no load. THD is the total hysteresis distortion of a selected transformer. THD is the ratio of the rms of the harmonic content to the rms value of the fundamental quantity, expressed as a percent of the fundamental. THD is the total rms harmonic current distortion, in percent of the maximum demand load current (15 or 30 min demand). - correct answer THD is the total rms harmonic current distortion, in percent of the maximum demand load current (15 or 30 min demand).***
When power is interrupted in a health care facility, what is the maximum amount of time allowed before power should restored by an alternate source? 5 seconds 10 seconds 30 seconds 60 seconds - correct answer 5 seconds*** Temporary protective grounds should be placed to create an equipotential zone ______. if concern for unexpected re-energization exists on the incoming lines near each energy source at the work location before any testing is performed - correct answer if concern for unexpected re-
