Power factor correction capacitors can reduce your energy costs by avoiding the premium rates electric utilities charge when your power factor falls below specified values. Facilities typically ...

FIGURE 1: This electrical schematic diagram shows the cooler’s single-phase, R-134a capacitor start/capacitor run (CSCR) refrigeration compressor motor, and starting relay circuit section. July 6, ...

The start capacitor will then stay in the circuit, which will cause high amp draws and can open motor protective devices. However, if the pick-up voltage generated by BEMF is above the maximum, the ...

While obvious bulging capacitors are easily identifiable, he discusses the need for an ESR meter and uses a kit-built model to test capacitors that do not have any visual signs of damage.

Circuit modeling can be an excellent way of helping engineers narrow down the likely cause of some antenna system problems. The key is accuracy in creating the model and a good eye for interpreting ...

Single-phase motor failures or malfunctions can often be traced to issues with the centrifugal switch, thermal switch, or capacitor (s). These problems can typically be fixed by servicing, repairing, ...

Capacitors in the level indicator circuits were common polarized electrolytic types. Tom decided the amplifier was worth repair, from both technical and financial perspectives.

IDEAL Electrical™, a leading manufacturer of tools and supplies for electricians, proudly unveils the SureTrace™ Circuit Tracer Pro – a flagship addition to its trusted SureTrace line that ...
