Every now and then you need to make your own capacitor. That includes choosing a dielectric for it, the insulating material that goes between the plates. One dielectric material that I use a lot is… ...

Ever wondered how engineers inspect capacitors, resistors, and inductors? The solution is frequently in a device known as an LCR meter. The tool is quite valuable since it measures three significant ...

Ceramic capacitors play an oversized role in circuit performance as a major contributor to voltage regulator control loop stability and power delivery network (PDN) impedance. When designing with ...

Most modern oscilloscopes can accurately measure the signals without loading the circuit, except for the capacitance of the probe. Capacitance is usually marked on the probe. Use the previous equation ...

In this op-amp-based capacitor measurement circuit, the op amp is driven in an astable fashion, triggering a hysteretic comparator to switching the polarity at two thresholds.

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 ...

A 9-V battery or an optional ac wall adapter can power the Model 881 portable in-circuit equivalent-series resistance (ESR) and dc resistance (DCR) capacitor tester. It measures ESR and DSR from 0 ...

ABB has released a new 145-kV high-voltage circuit breaker. The 145PM63-B high-voltage circuit breaker uses a new high-performance interrupter to serve 121-145 kV applications at 40-, 50-, and 63-kA ...

Northeast Power Systems, Inc. metal-enclosed capacitor banks are designed for industrial, commercial, and utility power systems requiring medium-voltage automatic power factor correction.

Technical Terms Capacitor Voltage Transformer (CVT): A device that employs capacitive voltage dividers to step down high voltages for measurement and monitoring in power systems.
