Overview 1.1 Scope This application guide covers procedures and calculations necessary to apply the standard transient recovery voltage (TRV)
32、 ratings for ac high-voltage circuit breakers rated above 1000 V. The breaking capability limits of these circuit breakers are determined to a great degree by the TRV. This application guide is not included in other existing circuit-breaker standards. In this document, the TRV ratings are compared w
33、ith typical system TRV duties. Examples of TRV calculation are given with suggested options if the TRV duty exceeds the TRV ratings of the circuit breaker. 1.2 Purpose The purpose of this standard is to provide an application guide on the TRV ratings given in IEEE Std C37.041for ac high-voltage circ
34、uit breakers rated on a symmetrical current basis. Definitions, rating structure, test procedures, and preferred transient voltage ratings and related required capabilities are included in IEEE Std C37.04, IEEE Std C37.06, IEEE Std C37.09, and ANSI C37.06.1. IEEE Std C37.010 applies in other respect

Transient recovery voltage 3.1 General The recovery voltage is the voltage that appears across the terminals of a pole of a circuit breaker after interruption. This voltage may be considered in t
41、wo successive time intervals: one during which a transient voltage exists (TRV), followed by a second during which a power-frequency voltage alone exists. During the interruption process the arc rapidly loses conductivity as the instantaneous current approaches zero. Within a few microseconds after
42、current zero, current stops flowing in the circuit. The power system response to current interruption generates the TRV. TRV is the difference in the power system response voltages on the source side and on the load side of the circuit breaker. The nature of the TRV is dependent on the circuit being
43、 interrupted, whether primarily resistive, capacitive, or inductive (or some combination). Additionally, distributed and lumped circuit elements will produce different TRV waveshapes. In principle, the response of the load side and source side of the circuit breaker can be analyzed separately and th
44、e results subtracted point by point on a time line. The driving voltage is the instantaneous power-frequency voltage across the circuit elements at the instant of current interruption. The breaking operation is successful if the circuit breaker is able to withstand the TRV and the power-frequency re
45、covery voltage. 2ANSI publications are available from the Customer Service Department, American National Standards Institute, 25 W. 43rd Street, 4th Floor, New York, NY 10036, USA (http:/www.ansi.org/). 3IEEE publications are available from the Institute of Electrical and Electronics Engineers, 445

47、 High-Voltage Circuit Breakers 3 Copyright 2011 IEEE. All rights reserved. TRVs can be oscillatory, triangular, or exponential, and can occur as a combination of these forms. The most severe oscillatory or exponential recovery voltages tend to occur across the first pole to open of a circuit breaker
48、 interrupting a three-phase symmetrical fault at its terminal when the system voltage is maximum. (See Annex C for more information on the TRV and power-frequency recovery voltage applied on each pole while interrupting a three-phase terminal fault.) The triangular recovery voltages are associated w
49、ith line faults. The initial rate of rise of the recovery voltages for line faults becomes greater the closer the fault is to the circuit breaker; however, the magnitude of this line-side triangular wave decreases as the rate of rise increases. Generally, the source recovery voltage is much slower and only the triangular recovery voltage is effective in the early time period of the TRV. The amplitude of the recovery voltages for these line faults is determined on a single-phase basis during their early time periods. By definition, TRV values defined in the
