Power Quality and Grounding Audit

An analysis of power sources and grounding networks

Detailed analysis of incoming power and grounding integrity identifies specific problem areas and provides recommendations to improve overall system performance.

Benefits

Improve plant safety
Eliminate transient power spikes
Revalidate power quality
Increase mean time between failures

Power Quality and Grounding Audits provide a detailed analysis of incoming power quality and grounding integrity and its effect on connected devices and internal power systems. Audit findings pinpoint specific problem areas and provide fixes that improve overall system performance.

Overview

Scope

If you have experienced unexpected system malfunctions or halts, system crashes, console failures, processor lockups, abnormally high parts failures, or unusual or floating readings, a system audit and reevaluation of power systems is recommended.

A full audit will identify ground faults, power quality deficiencies and improve overall system performance.

Reporting and recommendations

Upon completion, a findings report including detailed implementation recommendations to improve power and grounding related problems and associated cost is provided.

Upgrade services

ABB can help you with implementation of recommendations to enhance productivity. Our time-tested expertise in this area can help to revitalize electrical system efficiency to a level you may have considered to be out of reach.

Maintenance

ABB recommends that the Power Quality and Grounding Audit be performed annually as part of a comprehensive maintenance program.

Comprehensive scope

An audit begins with a review of system grounding installation documentation. Using state of the art test equipment, a careful review of the installation is then performed on the following:

Control system cabinets
AC distribution panel
Isolation transformer
Uninterruptible power supply
Bypass operations
Connection to building grounding system
Electrode to earth resistance where appropriate
Power quality including transients and harmonics
Ground loop problems

A careful disturbance analysis is conducted for an extended period to monitor transient activity and its effects on your equipment. Radio frequency interference (RFI) and electromagnetic interference (EMI) reviews can be provided in cases where unusual operation has indicated the likelihood of such interference.
