Section 12
Testing and Troubleshooting
Overview
This section provides guidelines for determining and establishing test routines
for the SEL-734 Meter. Included are discussions on testing philosophies,
methods, and tools. Meter self-tests and troubleshooting procedures are shown
at the end of the section.
Testing Philosophy
Revenue and Power Quality Meter testing may be divided into three
categories: acceptance, commissioning, and maintenance testing. The
categories are differentiated by when they take place in the life cycle of the
meter as well as by the test complexity.
The paragraphs below describe when to perform each type of test, the goals of
testing at that time, and the meter functions that you need to test at each point.
This information is intended as a guideline for testing SEL meters.
Acceptance Testing
When: Qualifying a meter model to be used on the electrical system.
Goals:
1. Ensure meter meets published critical performance
specifications, such as metering accuracy.
2. Ensure that the meter meets the requirements of the intended
application.
3. Gain familiarity with meter settings and capabilities.
What to Test: All elements and logic functions critical to the intended
application.
SEL performs detailed acceptance testing on all meter models and versions.
The meters we ship meet their published specifications. It is important for you
to perform acceptance testing on a meter if you are unfamiliar with its
operating theory or settings. This helps ensure the accuracy and correctness of
the meter settings when you issue them.
