OEM EXPRESS SWITCHGEARPOWER/VAC®—QUALITY, EXPERIENCE & RELIABLITYTAILORED TO THE NEEDS OF THE OEM

In 1977 General Electric introduced POWER/VAC® and trans-formed the metalclad switchgear industry. Clean quiet, reliable anddurable, POWER/VAC® metalclad switchgear offered significant ad-vantages over air magnetic designs. Now many companies offervacuum switchgear, many of them look like POWER/VAC®, but notone can match POWER/VAC’s years of in-service experience.

More Than 40 Yearsof Interrupter Experience

GE pioneered experimental vacuum interrupters in the 1920’s.Refined it and introduced the world’s first vacuum interrupter distribu-tion breaker in the 1960’s. To date, this interrupter design has beenthe world leader in vacuum technology and has accumulated over 35years of reliable field service. It’s the heart of thousands of POWER/VAC® breakers in service with ratings from 4.16kV - 250 MVA through13.8kV - 1500 MVA at 1200, 2000, 3000, 3500, and 4000 amps (fancooled).

World-wide AcceptancePOWER/VAC® metalclad switchgear is in service throughout the

U.S. and in dozens of other countries. Many installations are sub-jected to harsh operating environments: salt air abroad offshore plat-forms miles out to sea, high altitudes in the mountains of Chile,excessive heat at fertilizer plants in Trinidad, humidity at petro-pro-cessing operations in Venezuela, wind and sand at power plants,public works and oil exploration installations in Saudi Arabia. It isonline in paper mill, steel mills, cement mills, petro-chemical facili-ties and in electric utility systems the world over - wherever a highvalue is placed on reliability, POWER/VAC® is the industry acceptedleader.

Standardization Means High QualityA high degree of standardization has been achieved with POWER/

VAC® breakers. All breakers are the same size regardless of voltage orinterrupting capability. Additionally, most parts of the frame, primaryconductors, disconnects and mechanisms are interchangeable through-out the breaker product line. This results in a higher quality productand reduces training time for operating and maintenance personnel.

Interlock System ProtectsOperating Personnel

For personnel safety, POWER/VAC® breakers are designed with anumber of mechanical and electrical interlocks. For example, breakercontacts must be open before the breaker can be moved to or from theCONNECT position. A positive mechanical stop is provided when thebreaker reaches the CONNECT or TEST/ DISCONNECT positions.Mechanical interference interlocks are provided to permit only theinsertion of properly rated breakers into any specific compartment.These and other necessary interlocks provide a comprehensive protec-tion system. Futhermore, springs automatically discharge when thebreaker is withdrawn from the CONNECT position and breakers cannotbe inserted in the closed position. Closed door drawout design alsocontributes an extra measure of operator protection.

GE Medium Voltage Switchgear Application Data

Table 3.1.1 POWER/VAC® Circuit Breaker Characteristics


Notes Applying to Table 3.1.1

(1) Maximum voltage for which the breaker is designed and the upperlimit for operation.

(2) K is the ratio of rated maximum voltage to the lower limit of the rangeof operating voltage in which the required symmetrical and asymmetri-cal interrupting capabilities vary in inverse proportion to the operatingvoltage.

(3) To obtain the required symmetrical interrupting capability of a circuitbreaker at an operating voltage between 1/ K times rated maximum volt-age and rated maximum voltage, the following formula shall be used:

Required Symmetrical Interrupting Capability =Rated Short-circuit x (Rated Max. Voltage)

(Operating Voltage)

For operating voltages below 1/K times rated maximum voltage, therequired symmetrical interrupting capability of the circuit breaker shallbe equal to K times rated short-circuit current.

11

(4) With the limitation stated in 5.10 of ANSI - C37.04-1991, all values applyfor polyphase and line-to-line faults. For single phase-to-ground faults,the specific conditions stated in 5.10.2.3 of ANSI-C37.04-1991 apply.

(5) Current values in this column are not to be exceeded even for operatingvoltages below 1/K times rated maximum voltage. For voltages betweenrated maximum voltage and 1/ times rated maximum voltage, follow (3)above.

(6) NOTE: 1500 MVA not a listed rating according to ANSI C37.06 Table 2.1.
