T… The current state and measured parameters are sent to the remote IoT server by using the data reception subsystem. relay 51T = High Side Phase OC relay 51 = Low Side Phase OC relay 51G = Low Side Ground OC relay 51GB1,2 = Ground Backup OC relay 51G 51GB1 51 51GB2 51TG = High Side Ground OC relay 87K-S 87K-P 87K-S = Sec. protection of transmission lines[distance relay protection scheme], No public clipboards found for this slide, Electrical Engineer Technician at Kuwait Oil Company. Transformer Protection • Differential Protection • Current Transformer Performance • Through Fault Protection • Mechanical Protection. There are different kinds of transformers such as two winding or three winding electrical power transformers, auto transformer, regulating transformers, earthing transformers, rectifier transformers etc. Now customize the name of a clipboard to store your clips. 212 TRANSFORMER PROTECTION practically unanimous in approving differential relaying for banks rated 5000 kva and higher.2 To apply these recommendations to power autotransformers, the foregoing ratings should be taken as the Òequivalent physical sizeÓ of autotransformer banks, where 1. In the protection subsystem, Arduino controls the operation of a fan and protection relay to protect the transformer in a fault condition.

The electrical windings and the magnetic core in a transformer are subject to a number of different forces during operation, for example: Expansion and contraction due to thermal cycling Vibration Local heating due to magnetic flux Impact forces due to throu ASS Relays Power transformer protection AGO3-5005 E Page 6 The current in the short-circuited turns may be 50-100 times the rated current. Generators, transformers, lines, cables, busbars, motors) to form a defined zone of protection dictated by current transformer location. XProtection co-ordination is difficult / not possible using time delayed elements XFast fault clearance is critical Can be used on all items of plant in one form or another (i.e. overcurrent protection is available for each winding or measurement location of a transformer. The transformer is one of the major equipment in power system. If you continue browsing the site, you agree to the use of cookies on this website. It is normal for a modern relay to provide all of the required protection functions in a single package, in contrast to electromechanical types that would require several relays complete with interconnections and higher overall CT burdens.
