The Enhanced version of the software includes many of the test modules found previously in our AVTS Relay Library, and features a synchronizer test and frequency test (includes ROCOF). For these tests, the relay outputs are normally disconnected from the remainder of the protection scheme, as it is a test carried out to prove correct relay, rather than scheme, operation. The IRI1-IE is equipped with one trip relay for low set overcurrent one for high set overcurrent and one trip re-lay for earth-fault detection: Tripping I>: C1, D1, E1; C2, D2, E2 The Reyrolle 7SR10, 7SR11,7SR12,7SR21 and 7SR22 Argus overcurrent protection devices have been specifically designed to provide feeder protection for distribution and industrial networks.

From this basic method, the graded overcurrent relay protection system, discriminative short circuit protection, has been formulated. The extent of testing will be largely determined by the client specification and relay technology used, and may range from a simple check of the relay characteristic at a single point to a complete verification of the tripping Scribd is the world's largest social reading and publishing site. Paperback: 70 pages Trim Size: 8.5"x11" Relay protection against the high current was the earliest relay protection mechanism to develop. Automatic testing of positive/negative/zero sequence overcurrent characteristics Overcurrent is used for automatic testing of directional and non-directional overcurrent relays with auto-assessment of the trip time characteristic, the directional boundaries of the current stages, and the pick-up/drop-off ratio. If the circuit to be tested is in service, one relay at a time should be removed (if applicable) so as not to totally disable the protection.
