The voltage dependence of DC-driven self-sustaining oscillation behavior of a micro-electro-mechanical (MEM) relay makes it possible to influence the phase of oscillation by coupling the gate or body, ...

Learn about the most common types of overcurrent relays used in power systems, their pros and cons, and how they are coordinated and set.

An electromechanical, plunger type 50 relay is modelled in EMTP/ATP using TACS. Mechanical, magnetic, and electrical characteristics are represented in the form of simple mathematical models that can ...
