Power Logging & Monitoring

Services

What is Power Logging?

Power logging is the process of measuring and recording how electricity is used within a home, business, or industrial site over a specific period of time. Using a portable power logger or power analyser, an electrician can track voltage, current, power factor, demand peaks, and load balance across circuits. This data reveals how efficiently power is being used, where energy is being wasted, and whether the electrical system is performing safely and reliably.

In Perth, power logging is becoming an essential service for business owners, facilities managers, and homeowners who want to understand their energy use in detail. With rising energy costs and tighter compliance requirements, accurate power monitoring and reporting allows you to make informed decisions about upgrades, maintenance, and energy efficiency improvements.

When a power logger is installed, it continuously records your site’s electrical performance over several days or weeks. Once the data is collected, a licensed electrician analyses it to identify any abnormalities—such as unbalanced phases, equipment faults, excessive load spikes, or poor power factor correction. The final report provides clear, visual information on what’s happening behind the switchboard, often revealing issues that can’t be seen during a standard inspection.

Who has benefit from Power Logging Services?

Our power logging and monitoring services have helped clients across Perth understand their site’s energy capacity, prevent outages, and make smarter upgrade decisions. Here are some real examples of how our studies have delivered practical results and savings.

1. Cottesloe – 45-Unit Strata Complex

A large Cottesloe strata complex engaged our team to assess whether their existing electrical infrastructure could support air-conditioning installations for all 45 units. We completed two power monitoring studies—a seven-day test in winter and another in summer—to measure seasonal load variations.

The data revealed that the complex’s maximum demand peaked at only 40% of total capacity, leaving significant headroom for new installations. Our power logging report confirmed that 100% of units could safely add air-conditioning without overloading supply. We also provided a detailed list of viable cooling options and future energy considerations to maintain healthy operating levels across the site.

2. Mundaring – Shopping Complex & Local Businesses

In Mundaring, a shopping complex approached us to determine whether their existing distribution point could accommodate multiple electric vehicle (EV) chargers. We carried out a targeted power monitoring study to map current load profiles and usage patterns.

The results showed that the system could support the additional demand without major infrastructure upgrades. By identifying this early, the client saved tens of thousands of dollars in unnecessary cabling, labour, and downtime. The power logging Perth study allowed for a smooth EV rollout with minimal disruption to daily operations.

3. Perth CBD – Strata Complex with Regular Power Disruptions

A strata complex in the Perth CBD was experiencing ongoing and unexplained power interruptions affecting multiple units. We deployed our power monitoring equipment for a 21-day period to capture comprehensive electrical performance data across the site.

Following our detailed reporting, an electrical engineer reviewed the results and identified intricate harmonic distortion issues that were previously undetectable. This analysis enabled the engineer to design a cost-effective, permanent solution that restored stable power to the building. Without the power logging data, the underlying issue would have remained hidden and unresolved.

4. Bayswater – Survey Strata Complex with EV Charger Enquiries

At a six-unit survey strata complex in Bayswater, one resident requested a study to explore the potential for installing EV chargers across all properties. Our power monitoring assessment confirmed that the site did not have sufficient capacity for six 22 kW chargers running simultaneously.

However, through our report and consultation, we recommended a load management system that would safely distribute demand across all chargers. This approach allowed the installations to proceed while ensuring total load never exceeded the network’s safe operating limits—providing a practical, future-ready solution for the residents.
