Single-phase motors, adjustable-speed drives (ASDs), and power factor (PF) correction applications often depend on capacitors to operate properly. This article explains how to test these critical ...

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

The Quick-Check Transformer & Capacitor Tester is a versatile tool for quick and easy checks of capacitors, transformers and the connections made to them. In the field, the Quick-Check is used to test ...

Start capacitors are not designed to dissipate the heat associated with continuous operation; they are designed to stay in the circuit only momentarily while the motor is starting. If a start ...

Most simple circuits you'll find for measuring reactive components cover only a limited range of component values. Here's a circuit built from a handful of inexpensive parts that will let you measure ...

For as versatile and inexpensive as switch-mode power supplies are at all kinds of different tasks, they’re not always the ideal choice for every DC-DC circuit. Although they can do almost ...

Ceramic capacitors are small, they don’t leak, they’re convenient, but they are downright strange. Certain types of caps will lose their capacitance depending on the voltage they’… ...

The circuit shown here tackles ESL/ESR measurement of capacitors by using a mercury-wetted relay (Fig. 1). In this circuit, the relay is employed as a fast closing switch.

Capacitors are essential electrical components that are incorporated into just about every type of electronic hardware manufactured. They are widely used for bypassing, coupling, filtering, and ...

The Quick-Check Transformer & Capacitor Tester from HD Electric is a versatile tool for quick and easy checks of capacitors, transformers and the connections made to them. In the field, the ...
