    Description

    How to test the differential function (87 / PDIFF) with software resources that facilitate and automate the procedure?

    This software performs automatic tests on differential relays. A variety of predefined differential relay models (Masks) are registered in the software, allowing the user greater facilities for entering test data. However, if the relay is not registered, the compensation characteristics can be easily parameterized by selecting the restriction equation (Ibias), the TAPs compensation mode, correcting the angular lag and eliminating the zero sequence component.

    The user can configure the tests specifying which generation channels are directed to the windings from 1 (one) to 4 (four), can also enable fault conditions, and pre-fault conditions 1 and 2, in addition to having a trigger interface via software , binary input and GPS.

    The tests performed are: Configuration Test, Point Test and Search Test. For all tests it is possible to view the characteristic curve. The software also allows you to direct the Fault, Pre-Fault 1 and Pre-Fault 2 pulse conditions to the Binary and GOOSE outputs.

    In this software, the user has the ability to register which type of protected equipment (Transformer, Generator, Motor, Bus or Transmission Line). In addition to the three-phase tests for transformers with up to 4 windings and bars with up to 6 bays, it also allows single-phase tests for transformers and for bars with up to 18 bays.

    There is a register of voltages, powers, connections, vector group and grounding of the windings, in addition, of course, of the transformation relationships of the CT’s connected to the protected equipment.

    A very interesting feature are the “Systems” and “Relay Details” tabs. There the user has the possibility to check how the currents are inside and outside the relay, assisting in the differential analysis.
