41、n This introduction is not part of IEEE Std C37.103-2015, IEEE Guide for Differential and Polarizing Relay Circuit Testing. Errors in the wiring of connections to protective relays have caused erroneous operations of the associated protective schemes resulting in many serious power interruptions. In

42、 most cases, thorough testing would have discovered those incorrect connections. Ground relay polarizing and differential relay connections are the most troublesome and difficult to locate; therefore, this guide describes and discusses the issues concerning testing and verification of the correctnes

43、s of these circuits. This guide describes tests for helping to ensure correct differential and polarizing circuit connections. Relay calibration, setting, insulation, instrument transformer tests, etc., are also referred to in this guide, but it is assumed that the individual users have developed th

44、ese tests, and therefore they are not discussed in detail. Methods for testing differential and polarizing circuits have never really been defined by the manufacturers because a large variety of ways in which differential and polarized circuits are applied in relay systems. Consequently, utilities d

45、evelop their own testing techniques, which can vary widely depending on factors such as the availability of test switches, test gear, test philosophy, problems discovered in the past, and manpower. Good systematic testing should include systematic documentation of the tests and the test procedures.

46、This should include documentation of all measurements and a comparison with the desired results. Comments on the advantages and disadvantages of the different techniques are presented, and operating considerations for personnel and equipment are included. Since most of the circuit verification tests

47、 include passing current through either the current transformer primaries or secondaries, the voltage source to accomplish these tests varies. For primary testing that may include power transformer windings, the required source voltage will be substantial. For secondary testing, the source voltage m

48、ay be relatively low. For some of these circuit tests, variable voltages are needed. In each case, the source is identified and noted on the figure involved. Traditional electromechanical and solid-state differential relays made no provision for phase shifts in the transformers; the connections and

49、wiring had to be arranged so that the normal load currents flowing into the respective primary and secondary “restraint” windings were 180 out of phase. Further, some current transformer (CT) connections were not possible without the use of wye-delta auxiliary CTs or a zero- sequence trap (see IEEE Std C57.13.1). a, b, cElectromechanical and solid-state relays usually did not provide direct readout of the currents in the relays. In contrast, present microprocessor relays compensate for the transformer/CT connections and provide readouts from a front panel human-machine int
