SEL-387 Relay Differential Element Testing Aid - H Nurse 3/3/02 This sheet contains a few portions: - The first portion provides single phase test information similar to the IM section 10's testing information. - The second portion provides a balanced three phase test similar to the single phase test described above, this is desired by a few. - The third part allows simulated relay differential element testing using equivalent relay terminal winding. - Please note: Not all relay combinations and spreadsheet errors are addressed in this spreadsheet, use only as an aid, and ensure you satisfy yourself that the relay is correct independent of this aid. - The test sheet is protected without a password, normal operation does not require protection to be off, if defeated take care as hidden cells and indexing etc may be unknowingly be deleted and make the spreadsheet's calculations incorrect! Note: Only enter in yellow calculations protected.

SEL-587 Relay Differential Element Testing Aid - H Nurse 9/24/01 This sheet contains two portions: - The first portion provides single phase test information similar to the IM section 10's testing information. - The second part allows simulated relay differential element testing using equivalent relay terminal winding injected currents, the expected IOP and IRES for each 87R element is shown. - Please note: not all relay combinations and errors are addressed in this spreadsheet, use only as an aid, and ensure you satisfy yourself that the relay is correct independent of this aid. - For ACB phase rotation, exchange the IB and IC current as entered into part 2 Note: Only enter in yellow calculations protected.
