Ask most industrial facility managers when their site last had a load survey, and the answer is usually "never" — or "not since the building was commissioned." Yet load surveys are one of the most valuable tools available for understanding the true state of a site's electrical infrastructure, identifying inefficiencies, and preventing failures before they occur.

What Is a Load Survey?

A load survey is a measurement exercise that assesses the actual electrical load being drawn across your site's supply circuits over a defined period. Using calibrated data loggers and clamp meters, Abbcell's engineers measure current, voltage, power factor, and harmonic distortion at key points across your distribution system. The result is a detailed picture of how your electrical infrastructure is actually being used — as opposed to how it was originally designed to be used.

Why Most Industrial Sites Are Overdue One

Electrical systems in industrial and commercial buildings rarely stay static. Equipment is added, production processes change, and layouts are reconfigured — often without any review of the underlying electrical infrastructure. Over time, this leads to:

• Circuits operating close to or beyond their designed capacity

• Phase imbalance (see our article on phase balancing)

• Poor power factor, resulting in higher electricity bills

• Harmonics from variable speed drives and other equipment degrading supply quality

What We Do With the Data

A load survey report from Abbcell doesn't just present numbers — it translates findings into practical, prioritised recommendations. We identify which circuits need uprating, where energy is being wasted, and what remedial work would deliver the greatest return on investment.

When to Commission a Load Survey

Load surveys are particularly valuable before major new equipment installations, during compliance reviews, when energy costs have increased unexpectedly, or as part of a broader programme of electrical infrastructure improvement.
