While LEDs are common in voltage detection applications, I have never seen an LED circuit that is dedicated to indicating the presence of low values of current flow. This simple LED current sensor ...

A current transformer (CT) is a simple, practical and inexpensive means of detecting the presence of AC current. Detecting load current rather than applied voltage is a superior method of determining ...

Medium-voltage indicators (2-43 kV) keep workers away from voltage and lets them know if there’s voltage or not. The indicator is a single-phase device mounted onto each phase of a power bus. Energy ...

HDE's DVI-100 and DVI-500 Series Digital Voltage Indicators are designed to be used on both transmission and distribution systems in overhead and underground applications. HDE's DVI-100 and DVI-500 ...

Understanding the causes, similarities, and differences between current and voltage distortion will help you pinpoint most power quality problems. When a writer or speaker mentions harmonic distortion ...
