Amperage: The base unit of measurement for electrical current. Equal to voltage divided by load resistance and expressed in Amps
Amp: A measurement of the amount of Amperage.
Current: The amount of energy flowing through a conductive wire or being used by a load. Measured in Amps.
Demand: Your instantaneous power usage or how much power you are using at any given instant of time. Measured in kW.
kW: Kilowatts. One thousand watts of power used at any given instant of time. Normally used when reading demand.
kWh: Kilowatt-hour. One thousand watts of power used over the course of one hour. Normally used when reading usage.
Load: Where your power is going to or what is being powered by your source.
Phase: A single feed of electrical power, usually from a transformer.
2 Phase: Two feeds of electrical power, each running independently of each other.
3 Phase: Three feeds of electrical power, each running independently of each other.
Power factor: A percentage based number that gives you the true power consumed in a system. Tied into your VAR, utility companies generally charge extra if your power factor goes below 80%.
Source: Where your power is coming from. Usually from a power transformer, or a generator.
Transformer: A device that “transforms” voltage and current into useful voltage and current. Where your source generally comes from.
Usage: The amount of power consumed in a given period of time. Measured in kWh.
Voltage: The electric potential or potential difference. Expressed in volts.
Volt: A measurement of voltage.
VAR: Volt-Amp Reaction. Power losses due to inductive reactance in a system. How your power factor is determined.
Watt: The basic measurement of electrical power. Equal to voltage times current.
Amp: A measurement of the amount of Amperage.
Current: The amount of energy flowing through a conductive wire or being used by a load. Measured in Amps.
