A magnetic core is a piece of magnetic material with a high magnetic permeability used to confine and guide magnetic fields in electrical, electromechanical and magnetic devices such as electromagnets, transformers, electric motors, generators, inductors, loudspeakers, magnetic recording heads, and magnetic assemblies.
The heater core is made up of small piping that has numerous bends. Clogging of the piping may occur if the coolant system is not flushed or if the coolant is not changed regularly. If clogging occurs the heater core will not work properly. If coolant flow is restricted, heating capacity will be reduced or even lost altogether if the heater ...
ACCC (Aluminum Conductor Composite Core) is a registered trade mark for a type of "high-temperature low-sag" (HTLS) overhead power line conductor. Description CTC ...
Two effects cause core losses: hysteresis loss in the steel and eddy currents. Silicon steel has low hysteresis loss, and the laminated construction prevents eddy currents from flowing in the core, which dissipates power in the resistance of the steel. The efficiency of typical distribution transformers is between about 98 and 99 percent.
By comparison, with an inductor with a straight core, the magnetic field emerging from one end of the core has a long path through air to enter the other end. In addition, because the windings are relatively short and wound in a closed magnetic field, a toroidal transformer will have a lower secondary impedance which will increase efficiency ...
PVC-sheathed MICC cable. Conductor cross section area is 1.5 mm 2; overall diameter is 7.2 mm. Mineral-insulated cables at a panel board. Mineral-insulated copper-clad cable is a variety of electrical cable made from copper conductors inside a copper sheath, insulated by inorganic magnesium oxide powder.
A positive-temperature-coefficient heating element (PTC heating element), or self-regulating heater, is an electrical resistance heater whose resistance increases significantly with temperature. The name self-regulating heater comes from the tendency of such heating elements to maintain a constant temperature when supplied by a given voltage.
Sample cross-section of high tension power (pylon) line, showing 1 strand (7 wires) of steel surrounded by 4 concentric layers of aluminium. Aluminium conductor steel-reinforced cable (ACSR) is a type of high-capacity, high-strength stranded conductor typically used in overhead power lines.
