parts and fabrication of the switchgear. B. Fabricator: The assembler of the component parts and their interconnections,

complete with interior support and exterior shell to form a fully functional piece of equipment.

1.03 SYSTEM DESCRIPTION A. Description of Operation: 1. The switchgear’s microprocessor controls monitor electrical parameters

of normal and emergency feeders. 2. A selector switch on the face of the switchgear shall allow the facility

staff to select between the “Normal Closed-Transition” automatic operational mode, “Optional Open-Transition” automatic operational mode, and “Test” Closed-Transition operational mode.

3. In “Normal Closed-Transition” operating condition, the utility circuit breaker is in the closed position, the diesel-alternator circuit breaker is in the open position, the three feeder circuit breakers are in the closed position and the diesel-alternator unit is shut down. Sequence of transfer operation occurs as follows:

a. The voltage on any phase of the utility feeder drops below 85 percent of normal, initiating an adjustable time delay (set at 2 seconds) to over-ride voltage fluctuations and momentary outages.

b. At the end of the adjustable time delay, the diesel-alternator unit is signaled to automatically start.

c. All feeder circuit breakers shall open. d. A voltage-frequency device prevents transfer until the

emergency feeder voltage rises to 90 percent of normal and the frequency reaches 95% nominal.

e. The switchgear transfers load to the emergency feeder through opening the utility feeder circuit breaker and closing the diesel alternator circuit breaker.


1) Sequentially close each feeder circuit breaker with a 3 second adjustable delay between each closing. Feeder circuit breaker number three (3) shall close first.

f. Complete transition from onset of utility feeder failure to emergency feeder transfer shall not exceed 15 seconds.

g. Upon restoration of power from the utility source, transfer from emergency to utility feeder is initiated with an adjustable time delay (5-25 minutes) in the switchgear and transfer occurs without power interruption, through momentary interconnection of both power sources not exceeding 100 ms. No-Interruption Transfer is controlled by in-phase monitor and sensors confirming both sources are present and acceptable. 1) Controls ensure that closed-transition load transfer

closure occurs only when the 2 sources are within plus or minus 5 electrical degrees maximum, and plus or minus 5 percent maximum voltage difference. Exception: If the emergency power source should fail and the normal power source has been restored, retransfer to the normal source of power shall be immediate, by passing the retransfer delay timer.

h. The diesel alternator unit continues to run unloaded 7 minutes, after which the control equipment shuts down the engine and resets the system.

4. In “Optional Open-Transition” operating condition, the utility circuit

breaker is in the closed position, the diesel-alternator circuit breaker is in the open position, the three feeder circuit breakers are in the closed position and the diesel-alternator unit is shut down. Sequence of transfer operation occurs as follows:

a. The voltage on any phase of the normal feeder drops below 85 percent of normal, initiating an adjustable time delay (set at 2 seconds) to over-ride voltage fluctuations and momentary outages.

b. At the end of the adjustable time delay, the diesel-alternator unit is signaled to automatically start.

c. All feeder circuit breakers shall open. d. A voltage-frequency device prevents transfer until the

emergency feeder voltage rises to 90 percent of normal and the frequency reaches 95% nominal.

e. The switchgear transfers load to the emergency feeder through opening the utility feeder circuit breaker and closing the diesel alternator circuit breaker. 1) Sequentially close each feeder circuit breaker with a 3

second adjustable delay between each closing. Feeder circuit breaker number three (3) shall close first.

f. Complete transition from onset of utility feeder failure to emergency feeder transfer shall not exceed 15 seconds.

g. When voltage on all phases of the utility feeder is restored to 90 percent voltage, transfer from emergency to utility feeder is initiated with an adjustable time delay (5-25 minutes) in the switchgear and an adjustable programmed transition time delay.


1) Set the adjustable time delay for the programmed transition to 2 seconds.

2) Exception: If the emergency power source should fail and the normal power source has been restored, retransfer to the normal source of power shall be immediate, by passing the retransfer delay timer.

h. The diesel alternator unit continues to run unloaded 7 minutes, after which the control equipment shuts down the engine and resets the system.

5. In “Test” operating condition, the utility circuit breaker is in the closed

position, the diesel-alternator circuit breaker is in the open position, the three feeder circuit breakers are in the closed position and the diesel-alternator unit is shut down. Sequence of transfer operation occurs as follows:

a. At the end of the adjustable time delay, the diesel-alternator unit is signaled to automatically start.

b. A voltage-frequency device prevents transfer until the emergency feeder voltage rises to 90 percent of normal and the frequency reaches 95% nominal.

c. Transfer from utility to emergency feeder occurs without power interruption, through momentary interconnection of both power sources not exceeding 100 ms. No-Interruption Transfer is controlled by in-phase monitor and sensors confirming both sources are present and acceptable. 1) Controls ensure that closed-transition load transfer
