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 ...

We needed to detect motion in a commercial, stepper motor driven system and subsequently initiate motion in a servomotor based system we developed. Because both systems simulate human respiratory ...

Instrument transformers provide reliable and accurate input for the protection, control and monitoring of power grid assets such as motor control centers, UPS systems, utility metering, low and medium ...

Smart transformers are designed to help better manage power for cities, and the largest smart transformer in the world ...

In power distribution systems, three-phase transformer configuration directly impacts system reliability and load management.

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 ...

Pylons are an integral part of everyday life, and whilst many people complain about their “ugliness”, they perform essential functions that enable the population to have electricity in their homes and ...

Whenever a power or distribution transformer is isolated from the power system, it is probable that residual magnetism remains in the core due to the phase shift. However, residual magnetism also ...
