All electrical installations, devices and machines rely on the quality of electrical insulation. A failure of insulation usually leads to a failure of the system in which it is used, often with ...

Learn how ESA can be used to assess transformer health, detect faults, and improve power quality across various applications, including wind, solar, and industrial settings.

Omicron's CT Analyzer provides fast and cost-effective testing and verification of current transformers for protection and metering applications. It automatically determines all relevant current ...

Current transformer (CT) saturation presents a critical challenge in the realm of power system protection and automation. Under fault conditions, the magnetic core of a CT may become saturated, ...

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 ...

An autotransformer is a transformer having part of its winding included in both the input and output circuit. A simple autotransformer connection is shown in Fig. 1. Note that because there is a ...

The units feature an intuitive orange three-position (Operating, Shorting and Measuring) disconnect lever. Engaging the lever fully automatically short-circuits the transformer when using the required ...
