AUTOMATIC TRANSFER SWITCH RENTAL
Automatic Transfer Switches are an integral component in
Caterpillar Generator Sets and are responsible for transferring
power between Utility and Generator. Today every standby generator
set that is sold requires at least one ATS, and some cases require
multiple units.
Ring Power offers a broad range of transfer switch products that
are positioned to support virtually any type of emergency power
application from simple, single ATS installations to highly
complex, multi-ATS/generator switchgear systems. Available in sizes
ranging from 40 through 4000A, there is a CAT switch to suit every
project's needs.
Overall ATS Features Include:
- Open & Closed Transition
- Delayed Transition
- Bypass Isolation
- 40 through 4000A
- Mechanically Held Contactor
- 50/60 Hz 600 V Class
Maintenance for ATS Product
Good maintenance programs should involve all components of a
generator, including the Automatic Transfer Switch. There are
several reasons for regular maintenance. In some industries, it is
mandatory to perform, at the minimum, a weekly load test. This
basic test makes sure the ATS is capable of sending a start signal
to the generator and transferring the building load onto the
generator for a period of time set by the user. This simple
operation ensures the basic functionality of the ATS and generator.
However, it does not address other critical operations during the
life of the switch.
Early Detection of Problems
A preventive maintenance contract can help identify problems
before a failure occurs. Consider, for example, power cables,
contactor assemblies and interconnect wires. During the initial
installation, start-up and commissioning, particular attention is
given to the integrity of these components. However, after a period
of time, these components can deteriorate, vibrate loose or become
contaminated by the operational environment. If regular maintenance
is not performed, failure could occur, causing extensive damage to
the ATS, generator or downstream devices. This type of failure and
resulting costs, can be prevented if the switch is under a
maintenance contract.
A maintenance contract should include, but not be limited to,
the factory recommendations for testing and maintenance in the back
of the Cat Operation and Maintenance Manual for each switch. These
basic services will ensure high reliability and prolong the life of
your ATS.
