    High_voltage_circuit_breakers ebook
    The need for a second edition arises from the fact that, although it is generally
    recognized that circuit breakers represent a relatively mature technology there are
    some areas of thls technology where changes are inevitable and where some of
    these changes take place continuously. The area of circuit breaker standards is one
    in which substantial changes have taken place. These changes have been hven
    primarily by the need and the desire to aclueve a high level of harmonization be-
    tween the International (IEC) and the American (ANSI) Circuit Breaker Stan-
    dards.
    New standards have recently been published and revisions to some others
    are in the process of being approved by both organizations. However, as new re-
    quirements are being established for the new generations of equipment, it must be
    recognized that a significant number of circuit breakers had been designed to meet
    what are now obsolete standards. These circuit breakers are still in service and
    consequently there is a need for preserving this type of information. It is the hope
    that the readers will find this second edition to be usehl in providing a link be-
    tween the old and the new requirements and furthermore that it can be considered
    to be a valuable source of information and guidance for the application of the older
    equipment.
