Page Count: 38
scope:

This test procedure summarizes the various tests which are made on ac high-voltage circuit breakers, describes accepted methods used in making the tests, and specifies the test9 which will demonstrate ratings under American Natl Stds . It does not preclude the use of other equiva¬lent or more effective methods of demonstrating ratings. These tests are divided into the following classifications:

(1) Design tests

(2) Production tests

(3) Tests after delivery

(4) Field tests

(5) Conformance tests

Design Tests. Design tests are those tests made to determine the adequacy of the design of a particular type, style, or model of high-voltage circuit breaker to meet its assigned ratings and to operate satisfactorily under normal service conditions or under special conditions, if specified. Design tests are made only on repre¬sentative breakers to substantiate the ratings assigned to all other breakers of basically the same design, the same interrupters, the same contact speeds, and at least as good dielectric strength. These tests are not intended to be used as a part of normal production.

The applicable portions of these design tests may also be used to evaluate modifications of a previous design and to assure that performance has not been adversely affected. Test data from previous similar designs may be used for current designs, where appropriate.

Production Tests. Production tests are those tests made to check the quality and uniformity of the workmanship and materials used in the manufacture of high-voltage circuit breakers.

Tests after Delivery. Tests made by the pur¬chaser after delivery of the circuit breaker to supplement inspection in determining whether the breaker has arrived in good condition may consist of timing tests on closing, opening, and close-open no-load operations and low- frequency voltage withstand tests at 75 percent of the rated low-frequency withstand voltage.

Field Testa. Field tests are made on operating systems usually for the purpose of investigating the per-formance of circuit breakers under conditions which can¬not be duplicated in the factory. They are usually sup-plementary to factory tests and therefore may not provide a complete investigation of the breakers' capabilities. Emphasis is usually placed upon performance under the particular conditions for which the tests are made rather than upon a broad investigation, and the schedule and instrumentation adapted accordingly.

Conformance Tests. Conformance tests are those tests that are specifically made to demonstrate the conformance of a circuit breaker with these standards.

Purpose

The purposes of the test procedure are:

(1) To establish that a circuit breaker of the design on test can perform satisfactorily both electrically and mechanically up to the ratings assigned to it.

(2) To establish that production breakers have been adequately tested during manufacture and after assembly and that the breakers have characteristics essentially the same as the breaker of identical design which was sub· j ected to design tests.
