UPS Testing: the basics

static 300x187 UPS Testing: the basicsThere is a two-fold purpose for electrical testing on uninterruptable power systems (UPS) and their components. First, to check the installation and perform component and systems tests to ensure that the system functions properly when energized. The second purpose is to develop a set of baseline test results for comparison in future testing to identify equipment deterioration.

Once the above tests are complete, perform operational tests and measurements on the energized system.

Testing

Many of these initial tests are repeated periodically as part of the system maintenance program. Because of this, the completeness and clarity of the test reports is important as they supply baseline data for comparison with the results of the maintenance tests.

There are four categories of tests for electrical equipment: factory, acceptance, routine maintenance, and special maintenance.

Factory tests

Factory tests are performed at the factory to prove the equipment was manufactured properly and meets specific design parameters.

Acceptance tests

Acceptance tests are also proof tests performed on new equipment and systems usually after installation and before the equipment is turned on. These tests are run to determine whether the equipment is in compliance with specifications, to establish benchmarks for future tests, to determine the equipment was installed without damage, and to verify whether the equipment meets its intended design operation and limits.

Routine and special maintenance tests

Routine and special maintenance tests are run after the equipment has been in service for a certain amount of time to determine the degree of deterioration as operating time increases. Routine tests are performed on a periodic basis and special tests are performed on defective equipment to help determine the cause of a failure and/or the extent of the damage.
