How Energy Logging can save you time and money.

Energy logging records a site’s power draw (kW) and energy consumption (kWh) over time with a portable logger. The data identifies peak demand, poor power factor, and wasted consumption — the three biggest drivers of high electricity bills — and verifies both utility invoices and the savings from efficiency projects.

Power and energy logging explained

When a piece of equipment is operated, it instantaneously consumes a specific amount of power in watts (W) or kilowatts (kW). This power is accumulated over the operating time and expressed as energy consumed in kilowatt hours (kWh). Energy is what your electric utility charges for; there will be a standard charge from the utility per kilowatt hour. Utilities may have additional charges, such as peak demand, which is the maximum power demand over a defined period of time, often 15 or 30 minutes.

There may also be power factor charges, which are based on the effects of the inductive or capacitive loads in the facility. Optimising peak demand and power factor often results in lower monthly electricity bills. Our Three Phase Electrical Energy loggers have the capability to measure and characterise these effects, enabling you to analyse the results and save money.

Identify energy savings with power and energy logging

Electrical power usage is changing constantly. This means loads on the electricity network are changing, resulting in energy waste. Discovering the source of this waste enables you to develop strategies to reduce the waste. With three-phase power and energy loggers, you can find out where and when you are consuming power and put actions in place that ensure you’re using your energy efficiently. By continuously visually presenting power and energy usage, we can help you quickly and easily identify savings opportunities, providing a rapid return on your investment.

Need to do energy and power usage logging, but facing any of the following challenges?

• No knowing what logger will be suitable.
• Not enough space in the distribution board to fit in large CTs.
• Unaffordable, expensive logging equipment from well-known brands.
• Not sure if the logging equipment is accurate and reliable.

Our energy logging equipment will solve all these challenges for you.

• We have selected the best equipment to make your choice easy. With a large range of Rogowski coils that can measure anything from 1 A to 10 000 A.
• Rogowski coils are much easier to install than large bulky CTs (Current Transformers) It is flexible enough to fit into tight spaces.
• The most important aspect to consider when buying a logger is how accurate it is. If calibration certificates are available from known and respected calibration labs, then the accuracy of the meter can be trusted.
• It is not necessary to go for a well-known expensive brand to get accurate, reliable equipment; cost-effective equipment can be just as reliable and accurate.

Energy logging can be used in the following three main areas.

• Energy efficiency
• Backup power and renewable energy
• Verification of electricity bills

Energy logging for energy efficiency

Investing in energy logging services for energy efficiency optimisation purposes has several advantages.

• Identify opportunities for energy savings.
• Know the amount of electricity used.
• Know where and when energy is being wasted.
• Identify the highest return energy usage optimisation interventions.

Energy logging for backup power and renewable energy

Planning to install backup power or renewable energy? Start by investing in energy logging services.

• Determine the size of the inverter or generator that is required for backup power.
• Determine the amount of energy storage required for a certain amount of backup time for your requirements.
• Determine if the grid power is in an acceptable range for grid-tied inverters to work, for example, voltage fluctuations.
• Identification of potential savings generated by solar power systems.

Energy logging for verification of electricity bills

If you suspect that you are not being billed accurately for the electricity you are using.

• Identify if energy usage per month corresponds to electricity bills.
• Identify if peak demand charges are accurate.
