How to Size a Current Transformer

The Current Transformer (CT) is used to sense AC current in single-phase or three-phase circuits. In the basic instrument-grade current transformer, a single primary conductor passes through the core. The secondary winding has multiple turns to provide a lower output current,

Differences Between LCD and LED Displays

Digital Panel Meter

Digital panel meters (or DPM) typically uses either an LCD (Liquid Crystal Display) or LED (Light-Emitting Diodes) to display information in an alphanumerical format. What are the differences between LCD’s and LED’s and how do you know which one to pick for your application?

Taut-Band Suspension System vs Pivot and Jewel Mechanisms
The frictionless, shock-proof, taut-band suspension system has demonstrated superiority over the pivot-and-jewel mechanism in all types of analog panel meters.

Digital Bargraph Meters

Analog Panel Meter

Indication Measurements of process parameters have historically been accomplished by the analog panel meter (APM). Since 1819, when Oersted proved the existence of current in a wire by using a compass needle positioned next to a conductor,

Managing Transformer Temperatures with An Intelligent Transformer Monitor

Average loading on transformers is increasing as utilities strive for higher asset utilization. Higher loads mean hotter operation and the need for improved thermal management. Intelligent transformer monitors, such as the Weschler Transformer Advantage,
