Single-phase motors are common in many industries and can be found in blowers, pumps, fans, lathes, and numerous other types of equipment. Single-phase motor failures or malfunctions can often be ...

The capacitor meter presented here can measure capacities between 100pF and 1uF on five areas of measurement, more we can say multimeter or tester. Circuit consists of an oscillator with variable ...

When it comes to the most typical cause of poor power factor in a facility, motor inductance is a likely culprit. The problem worsens when motors are not loaded to their full capacity. Harmonic ...

Back in the early days of electricity, lab workers could measure electric current in a circuit using an ammeter (galvanometer) and voltage using a voltmeter. From there, they could calculate ...

This LC meter circuit can measure coils and capacitors. When Lx or Cx is connected in the circuit the oscillator frequency will decrease and this decrease is measured by a frequency-voltage converter ...

Guest columnist Dale Cigoy, lead applications engineer at Keithley Instruments, outlines how an understanding of the challenges for testing capacitors can be invaluable to engineers. Capacitors are ...
