This testing includes the simulation of conditions or events that are associated with a device's input power leads (Mains).
Types of Power
AC single phase	AC multi-phase	50Hz, 60Hz or 400Hz	DC power system
Mobile Electrical Systems Simulated
Aircraft	Ships	Submarines	Land vehicles.
Terrestrial Environments Simulated
Light Industrial	Residential	Heavy Industrial	Telco Central Office
Externally Generated Disturbances
Drop Outs		The momentary loss of power.
Power Line Transients		Short duration events superimposed on the power lines.
Power Line Variations		Long term events encountered on power lines.
Ripple		Sinusoidal noise superimposed on the power line.
Electrical Fast Transients		Switching transients found on power lines.
Frequency Transients		Momentary changes in the power line frequency.
Voltage Sags		Momentary input power dips.
Voltage Surges		Momentary input power rises.
Test Specimen Characteristics
Dielectric Withstanding Voltage		A measurement of the impedance of insulating materials.
Insulation Resistance		A measurement of the resistance of insulating materials.
Efficiency		The ratio of work to electrical power.
Power Factor		The ratio of true power (Watts) to apparent power (VA).
Leakage Current		The measurement of undesired current flowing in the ground circuit.
Test Specimen Generated Disturbances
Clicks		Electrical noise transmitted from a test specimen back onto the power lines.
Flicker		Signals which cause lights to flicker are measured.
Harmonics		Harmonics are measured in either the frequency domain or time domain.
In Rush Current		The momentary current surge that may occur when a device is initially energized.
Power Quality		Measurements are made of the effect your product has on the power line quality. (e.g.: phase angle, load imbalance, harmonics, crest factor, etc.)
