The Fluorescent Lamp Circuit - Circuits and Systems I: Fundamental
... power consumed by the lamp. The calculation also shows that the electrical charge which passes through the lamp during a half cycle, rather than the average power being consumed by the lamp, is the most fundamental parameter in the theory based on the hardlimiter model. The high harmonic currents, w ...

Out-of-Step Protection for Generators
... In general, the protection normally applied in the generator zone, such as differential relaying, time delay system backup etc., will not protect a generator during a loss of synchronism. The loss of excitation relay may provide some degree of protection but can not be relied on to detect generator ...

Transformer types
A variety of types of electrical transformer are made for different purposes. Despite their design differences, the various types employ the same basic principle as discovered in 1831 by Michael Faraday, and share several key functional parts.
