Switching of mixed resistive and inductive loads, including moderate overloads: 60947-3 AC-23: Switching of motor loads or other highly inductive loads: 60947-3 AC-31A AC-31B ³) Non-inductive or weakly inductive loads 60947-6-1 AC-33A AC33B³) Motor loads or mixed loads including motors, resistors and up to 30% incandescent lamp load 60947-6-1 ...
An inductive load includes inductive (lagging power factor) loads. An inductive load consists of an iron-core reactive element which, when used in conjunction with a resistive load bank, creates a lagging power factor load. Typically, the inductive load will be rated at a numeric value 75% that of the corresponding resistive load such that when ...
When a transformer, electric motor, electromagnet, or other inductive load is switched off, the inductor increases the voltage across the switch or breaker and cause extended arcing. When a transformer is switched off on its primary side, inductive kick produces a voltage spike on the secondary that can damage insulation and connected loads.
The main commercial benefit when installing VO units, is on inductive loads, like motors which run pumps, fans and the like. [citation needed] In the home, the potential energy saving can be up to 12% on electricity bills. A VO device will lower the voltage to the most efficient level to maximise the savings on electricity consumption, so you ...
If an electric circuit has an output port, a pair of terminals that produces an electrical signal, the circuit connected to this terminal (or its input impedance) is the load. For example, if a CD player is connected to an amplifier, the CD player is the source, and the amplifier is the load, [2] and to continue the concept, if loudspeakers are ...
Diagram of a simple circuit with an inductance L and a flyback diode D.The resistor R represents the resistance of the inductor's windings. A flyback diode is any diode connected across an inductor used to eliminate flyback, which is the sudden voltage spike seen across an inductive load when its supply current is suddenly reduced or interrupted.
Pre-charge of the powerline voltages in a high voltage DC application is a preliminary mode which limits the inrush current during the power up procedure. A high-voltage system with a large capacitive load can be exposed to high electric current during initial turn-on.
In electronics, electric power and telecommunication, coupling is the transfer of electrical energy from one circuit to another, or between parts of a circuit. Coupling can be deliberate as part of the function of the circuit, or it may be undesirable, for instance due to coupling to stray fields.
