The Principle Behind Electromechanical Relays
A relay is similar to a switch, it is either open or closed. When the switch is open no current passes through the relay, the circuit is open, and the load that is connected to the relay receives no power. When a relay is closed, the circuit is completed and cur ....etc

MODELING RELAYS FOR POWER SYSTEM
PROTECTION STUDIES
by
SANDRO GIANNY AQUILES PEREZ
ABSTRACT
Numerical relays are the result of the application of microprocessor technology in relay
industry. Numerical relays have the ability to communicate with its peers, are
economical and are easy to operate, adjust and repair. Modeling of digital and
numerical relays is important to adjust and settle protection equipment in electrical
facilities and to train protection personnel. Designing of numerical relays ....etc
