Losses in electrical systems Losses in electrical systems In an electrical or electronic circuit or power system, losses can be classified into two categories: technical and non-technical losses. The term technical losses refers to part of the energy in play dissipates by unwanted effects, including energy lost by unwanted heating of resistive components (electricity is also used for the intention of heating, which is not a loss), the effect of parasitic elements (resistance, capacitance, and inductance), skin effect, losses in the windings and cores of transformers due to resistive heating and magnetic losses caused by eddy currents, hysteresis, unwanted radiation, dielectric loss, corona discharge,
Electrical discharge machining due to eroded brass particles causing "brass on brass" wire breakage, therefore copper is recommended. Several manufacturers produce EDM machines for the specific purpose of removing broken tools (drill bits, taps, bolts and studs) from work pieces. In this application, the process is termed "metal disintegration machining" or MDM. The metal disintegration process removes only the center of the tap, bolt or stud leaving the hole intact and allowing a part to be reclaimed. Closed loop manufacturing can improve the accuracy and reduce the tool costs Advantages of EDM include machining of: Disadvantages of EDM include: Electrical discharge machining Electrical
