Transfer Switch &Circuit Breakers

An automatic transfer switch is designed for connecting a critical load between 2 dissimilar power sources (that can be up to 180 degrees out of phase) when either source is not acceptable.

A circuit breaker’s designed function is to disconnect the circuit (conductors) and the load from the power source under overcurrent conditions.

Transfer CategoriesTransfer Categories All transfers can be placed in one of two categories

Transfer between two “live” sources

test transfer

re-transfer to normal

Transfer from a “dead” source to a “live” source

occurs as a result of a source failure

how dead is dead?

These categories apply regardless of the type of switching used

Page 30: Asco training

Network PowerASCO

Open Transition TransferOpen Transition Transfer “Break Before Make” switching

Load is disconnected for a finite period of time

Open transition -- step by step

transfer initiated

operator energized

TS mechanism begins to move

if transfer is between two live sources, an arc is formed

if transfer is from a dead source, load is disconnected

arc extinguished (if leaving a live source)

TS connects load to new source

several factors including the size of the motor, the inertia of the motor and the size of the non-

initiates transfer so that the sources will be within 60 degrees of each other when re-connection occurs

Implications of Seismic LoadsImplications of Seismic Loads Keep in mind the IBC

(International Building Code) replaces the UBC (Uniform Building Code)1997 edition

Section 1621.1.6 of the 2003 International Building Code is clear:

Importance Factor (Ip) 1.5, Life – Safety Component is required to function after an earthquake

Page 63: Asco training

Network PowerASCO

PowerTechnologies

Who’s Responsible?Who’s Responsible? The IBC clearly states that it is the responsibility of:

Equipment manufactures

Suppliers

Installers

Design Team Managers

To insure that their component remains “on line and functional”, after the emergency has occurred!

Specification Qualifications cont’dSpecification Qualifications cont’d Specific

Uniform Building Code (UBC)/International Building Code (IBC)

The equipment and major components shall be suitable for and certified to meet all applicable seismic requirements of the Uniform Building Code (UBC)/International Building Code (IBC) 2003 for zone 4 application. Guidelines for the installation consistent with these requirements shall be provided by the switchgear manufacturer and be based upon testing of representative equipment. The test response spectrum shall be based upon 5% minimum damping factor, UBC: a peak of 2.15g’s (3.2-11Hz), and a ZPA of 0.86g’s applied at the base of the equipment. The tests shall fully envelop this response spectrum for all equipment natural frequencies up to at less 35Hz. The transfer switch shall operate functionally both before, during, and after a seismic event.

Benefits of Connectivity ModuleBenefits of Connectivity Module Total No. of devices per LAN will not be limited to 32.

Therefore the number of dedicated LAN’s will be reduced.

Remote monitoring of transfer switches and other devices.

Ethernet is the “de-facto” standard for local and wide area network

Computers come with Ethernet built-in. Therefore no need for Serial Card setup.

Many different types of Device/Application protocols at different serial baud rates can be brought on one Ethernet wire for example: ASCO I, II and Modbus at different baud rates, 2 wire or 4 wire devices will be connected to a single “Ethernet LAN.”

Potential savings for building owners for huge wiring costs.

Standard commercially available LAN/WAN diagnostics tools will be utilized for troubleshooting.

Ethernet LANs can be extended to miles with commercially available Ethernet repeaters and fiber cables.
