|Alternating Current (AC)
||Alternating current is electrical current that continually reverses direction. Change in direction is
expressed in cycles per second.
||An Amp is a unit that measures the rate of flow of an electrical current.
||A breaker is a device that connects/disconnects power to a circuit.
||A Brownout is a temporary drop in electric power. Although power is not completely lost, a
brownout can cause significant data loss and voltage fluctuations
||A circuit is a continuous loop of current.
||A Circuit Breaker is a switch that protects the load from overcurrent conditions.
||The Critical Load is know to be the devices or equipment that has or will fail as a result of power
loss/power problems; subsequently causing loss of data or function and promoting unsafe
||Direct Current is the movement of an electrical charge in one direction.
||A fault is a short circuit in the power system.
||A ground references the connection of an electric circuit to the earth.
||Harmonic Distortion refers to the distortion of the sine wave.
||Hertz is a unit of frequency; one hertz is equal to one cycle per second.
|Hot, Neutral, Ground
||The Hot, Neutral, and the Ground are the three most common wires in a circuit.
||An inverter is an electronic device that produces alternating current (AC) from direct current (DC)
||A load is any device that requires energy.
||Noise is known as electrical signals that produce negative effects in the circuits of the electronic
||Overvoltage is typically described as any voltage value of 10% above nominal for at least a minute.
||Power Conditioning is the isolation of sensitive equipment from the effects of electrical noise and
voltage fluctuations otherwise referred to as "dirty power"
||Power Factor is the ratio of watts (W) to voltamperes (VA).
||A rectifier is a device that converts AC power to DC power.
||A sag is a decrease in voltage or current.
||A short circuit usually causes a circuit breaker to blow. A short circuit is inevitable when the
electric current does not reach the powered device.
||A surge is a short transient wave of current/power in an electrical circuit.
||An undervoltage is a measured voltage that falls below the nominal voltage for more than one
||An Uninterruptible Power Supply (UPS) is a system that most often uses batteries to supply
continuous power to a load when the utility is not present or is not at an acceptable level.
||A volt is a measurement of electrical pressure.
||Voltage Distortion is the distortion of the alternating current (AC) voltage.
||Watts is the measurement of the amount of electrical power drawn by the load
