A form of measurement that measures energy and refers to the amount of energy that is required to increase the temperature of a pound of water by one degree Fahrenheit.
Device which has a hermetically sealed motor close-coupled to the pump body associated with high elevation differences.
The ratio of working power, measured in kilowatts (KW) to apparent power, measured in kilovolt amperes (KVA.)
Power that sets up the magnetic fields in transformers, motors, etc. Also called "Reactive Power."
The amount of time it takes to recover the cost of an investment.
Shows the relationship between voltage, current, and resistance in a simple electrical circuit. It applies to both AC and DC circuits.
Is a ratio of how well the motor converts electrical energy into mechanical energy and is calculated by dividing the power into the motor by the power out of the motor.
Device that can vary the speed of a normally fixed speed motor.
SI unit of power, equivalent to one joule per second, corresponding to the power in an electric circuit in which the potential differences is one volt and the current one ampere.
Is energy from sources that are naturally replenishing but flow-limited; renewable resources are virtually inexhaustible in duration but limited in the amount of energy that is available per unit of time.
A device that is used to measure voltage, current, and resistance.
The ratio of cooling output of an air conditioner over a typical cooling season, divided by the energy it uses in watt-hours.
A fast-acting internal breaker that reduces the risk of shock in wet areas.
Is a semiconductor light source that emits light when flows through it.
Combination of KW and KVAR called "Apparent Power."
