The resetting time can be reduced and overshoots can be reduced due to absence of mechanical inertia and thermal storage. … 1 relay can perform only 1 function. The performance of static relay is better than electromagnetic relays as they are fast acting and accuracy of measurement is better than electromagnetic relay. This is because transistor can be used as an amplifying device as well as a switching device. Since the introduction of solid-state relays some decades ago, the debate over which is better, solid-state relays (SSRs) or electromechanical relays (EMRs), has gone on. The magnetic field then uses for opening and closing the switch and for performing the mechanical operation. The over or under current and voltage protection of various a.c.and d.c.equipments. The coupling, between the input circuit and the output circuit, is optical. The use of printed circuits eliminates the wiring errors and mass production is possible. The disadvantages of Electro-mechanical relays are. a power switching solution that can be used to allocate power without manually opening and closing the switch _���ޑ�n踌�x�K���4�R�? Electromagnetic relays are those relays which are operated by electromagnetic action. Thus they are bulky in size. Hence, the Potential and the Current Transformers should have a higher capacity. The moving parts are absent. The distinction between digital and numerical relays is particular to Protection. Since that time, it has gradually evolved from very large, relatively crude parts to the small, ultra-reliable parts we have today. When the operating current becomes large, the magnetic field produced by electromagnet is high such that this magnetic field pulls the armature or plunger making the trip circuit contacts to close. Hence there is no mechanical noise. What are the advantages of static relay over electromagnetic relay? The power consumption is very low as most of the circuits are electronic. The advantages of solid-state relays include the following: •SSRs are typically smaller than EMRs, conserving valuable real estate in printed-circuit board applica- tions †SSRs offer improved system reliability because they have no moving parts or contacts to degrade As moving parts are absent, the minimum maintenance is required. In fact, both of them provide isolation between the input and output circuit. The static relays are replacing all electromagnetic relays like induction cup relays for distance and directional protection and disc relays for over current protection (except the attracted armature relays and DC polarized relays), because these relays control can many circuits at low costs. endstream endobj 163 0 obj <> endobj 164 0 obj <>/ExtGState<>/Font<>/ProcSet[/PDF/Text/ImageC/ImageI]/Properties<>/XObject<>>>/Rotate 0/Type/Page>> endobj 165 0 obj <>stream The reed relay was invented in 1936 by Bell Telephone Laboratories.
