protective relay tutorial

A relay has three main controls. have multiple functions, and logic that used to be contained in wiring diagrams or control schematics now resides in relay settings. January 24, 2020 at 4:54 pm A relay is automatic device which senses an abnormal condition of electrical circuit and closes its contacts. Definition of Protective Relay. Alternatively, 0.15A is the minimum diff current required for relay operation if the system loading is 0.5A (sec). Irest= 0.3 x 0.5 = 0.15A (see point P on the restraint characteristic). the offer for DIGSI 4 training – DIGSI 5 training and IEC 61850 training packages has been sent to your email. Setting procedures are only discussed in a general nature in the material to follow. 2 Your Presenters Terrence Smith Terrence.Smith@GE.com 423-304-0843 Craig Wester Craig.Wester@GE.com 678-591-5018 6 tools you MUST learn before programming numerical protection relays for real (photo credit: Lucy Electric) A basic understanding of Boolean expressions and methodologies is helpful in developing the required programing to obtain the desired logic and for effectively using the full power that is designed into numerical relays. These controls are Logic operation, on off control, Limit control. The Protective Relay Training course provides basic guidelines for relay application and settings calculation. These contacts in turns close and complete the circuit breaker trip coil circuit hence make the circuit breaker tripped for disconnecting the faulty portion of the electrical circuit from rest of the healthy circuit. During study of electrical protective relays, some special terms are frequently used. Thanks Hayder, I ll update you for protection relay raining package and ABB PCM 600 as well as Easergy Studio training. The relay will now use 30% of this ITOTto derive its actual restraint current, i.e. Principles are emphasized. Time setting multiplier (TSM). Plug setting multiplier (PSM). overloads, reverse, under current, over current etc. Commissioning protective relays has changed with the increased use of microprocessor Many relays -based relays. PR Protection Relay CB Circuit Breaker Equip Protected Item CT Current Transformer VT Voltage Transformer DC Aux DC Auxiliary supply HMI Man-machine interface PCL Communications Link Tr CB trip coil The two primary protective equipment components used in the isolation of faults and abnormalities are circuit breakers, and protective relays. For example, protective relay is able to save the damaging of equipment by sensing the abnormalities e.g. Now if IDIFF> 0.15A relay operation results. ADITYA LAGUDU. However, the newer relays also provide many advantages in commissioning, including: • Transformer Protection Application Guide This guide focuses primarily on application of protective relays for the protection of power transformers, with an emphasis on the most prevalent protection schemes and transformers. differential protective relay (power system device function numbers) A protective relay that functions on a percentage or phase angle or other quantitative difference of two currents or of some other electrical quantities directional control (as applied to a protective relay or relay scheme) It also reviews basic power system concepts and describes instrument transformers.
