Capacitive sensors are found in a wide range of equipment, from consumer electronics to industrial/process control. Touch buttons are increasingly found in lamps and dimmers. Motion detectors can ...

This video explains what capacitors are and how they store and release electrical energy in electronic circuits. Capacitors ...

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 ...

Capacitor Voltage Transformers (CVTs) are central to modern power systems, where they not only scale high transmission voltages into measurable signals but also ensure the precision needed for ...

Using a PN-junction diode for temperature measurement usually depends on its 2‑mV/K temperature coefficient. Conventionally, you must amplify and digitize this voltage with an ADC before you can use ...

Northeast Power Systems, Inc. metal-enclosed capacitor banks are designed for industrial, commercial, and utility power systems requiring medium-voltage automatic power factor correction. Oct. 16, ...

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 ...

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 ...
