EPMS commissioning: looking beyond the dashboard
Screen electrical power monitoring engineers for measurement scope, event timestamps, integration, evidence and commissioning responsibilities.
01
Separate monitoring from protection and control
An electrical power monitoring system can provide measurements, alarms and event records, but project architectures differ. Do not assume it owns protective functions or switching commands. Ask the candidate to describe the actual boundary.
Identify the meters, intelligent devices, gateways and supervisory software involved, without treating a protocol or product name as proof of successful commissioning.
02
Ask how the data was trusted
Use one nonconfidential example of a measurement or event that the candidate verified.
- What was the source device and which approved reference applied?
- How were naming, scaling, units and device mapping checked?
- How were time alignment and event order evaluated where required?
- What happened when the displayed data disagreed with another record?
- Who owned configuration changes and how was the result retested?
03
Connect EPMS work to integrated testing
ASHRAE notes the value of controls and measurement records during L4 and L5 testing and as a baseline for operations. Ask how the EPMS evidence supported the test record, and what its limitations were.
Familiarity with event logs does not authorize relay-setting changes or work on energized equipment. Verify specialist qualifications and site authority independently where the role requires them.
Quick answers
Common questions
- Can a dashboard show plausible but wrong values?
- A display alone does not establish correctness. Ask what source checks, mapping checks and acceptance evidence were used on the project.
- Should EPMS engineers have electrical knowledge?
- The required depth depends on the assignment. State the electrical systems and interpretation responsibilities in the brief rather than assuming a universal competency level.
