Energy Monitoring From FourJaw

FourJaw's Energy Monitoring feature enables manufacturers to understand their energy usage by providing the data insight to make informed decisions about how to reduce wasted energy usage, helping them to cut energy costs and become more sustainable.

Unlike a standalone Energy Monitoring system, FourJaw combines Energy Usage Data and Machine Usage Data to drive sustainable, productive and profitable manufacturing.


Why Use Energy Monitoring?

By combining energy usage data and machine usage data, FourJaw's Energy Monitoring feature provides a number of financial, process, cultural and environmental benefits.

Energy Consumption

Understand how much energy is used by machines, cells or factories.

  • Track energy usage trends and make informed decisions to reduce usage and improve efficiency
  • Energy consumption in some operations is proportionally a large amount of the overall manufacturing costs. Understanding the cost on a part-by-part basis enables more accurate costing meaning you can understand the margin quicker

Carbon Footprint

Understand your carbon footprint by machine.

  • Provide evidence of energy use reduction to regulatory bodies e.g. Climate Change Agreements with the Environment Agency (UK)
  • Assess the carbon impact of equipment to inform sustainability decisions and meet benchmarks

Cost of Energy Used

Understand how much the energy you've used has cost.

  • Reduce the cost of production by understanding the cost of energy and reducing unproductive downtime
  • Understand what work is most profitable and how to quote more accurately

Energy Efficiency Ranking

Rank machines by energy efficiency.

  • FourJaw's Energy Efficiency Metric combines energy use and productivity data to rank machines by energy efficiency

Frequently Asked Questions

How Accurate is FourJaw Energy Monitoring?

The accuracy of the energy use values will depend on the accuracy of the power factor of your machines plus the accuracy of the current clamp measurement.

FourJaw current clamps have been independently tested and in the range of 1 - 100 Amps, the accuracy is +/- 5.5%.

Energy monitoring in this way is accurate enough to show you trends and anomalies. For applications requiring more accurate data on energy monitoring, you can scale the energy use stated by FourJaw to that given by an accurately calibrated ammeter by changing the power factor of the machine.

Will FourJaw Energy Monitoring work on all my machines?

Current Range
The current clamps we use work on any machine where each phase has a current draw from 50mA-100A.

3-phase or 1-Phase
If your machine uses 3-phase electricity, simply clamp around one phase of the main incoming supply and make sure the machine has 3-phase chosen within the FourJaw energy settings. If 1-phase, clamp to either the live or neutral, but not both at the same time, and choose 1-phase in settings. 

Age, Make and Model
The age, make or model of the machine doesn’t impact the efficacy of the FourJaw platform.

Sometimes to optimise productivity and energy monitoring at the same time, the current clamps need to be moved to be on both the power supply and a particular spindle. If this is the case, our support team will work with you to get this right.

How do you calculate Energy Used, Cost and Carbon Footprint?

We calculate power usage as follows:

Single Phase
P = pf × I × V / 1000
In this formula, the amount of power - P (in kW) is equal to the power factor of the load (pf) multiplied by the phase current measured in Amps (A), multiplied by the Root Mean Square (RMS) line-to-line voltage (V), and divided by 1000.

P (kW)= √3 × pf × I × V /1000
The power - P (in kW) equals the square root of three (√3) multiplied by the power factor (pf) multiplied by the current in Amps (A), multiplied by the Root Mean Square (RMS) line-to-line voltage (V) divided by 1000.

To calculate the cost:
We multiply the power used by the cost per kWh given on the settings page.

To calculate the carbon footprint:
We multiply the power used by the kilograms of carbon equivalent per kWh given on the settings page. This is defaulted to the UK government-approved value.

Why Is Energy Monitoring Important for Manufacturers? Closely tracking and analysing energy consumption patterns gives manufacturers valuable insights into their usage trends and helps to identify areas for improvement. Monitoring energy allows production managers to optimise consumption rates and make informed decisions that lead to reduced energy costs and, often, increased efficiency.

Monitoring energy usage rates means manufacturers can identify inefficiencies, equipment malfunctions, or process bottlenecks, and take action to mitigate them. This proactive approach not only helps save on energy costs but also enhances overall efficiency.

Energy monitoring, equally, plays an important role in promoting sustainability and environmental responsibility. By monitoring energy consumption, businesses can identify opportunities for energy savings, reduce their carbon footprint, and fulfil sustainability goals.
How Monitoring Energy Consumption Can Improve Usage Rates

Energy monitoring empowers production managers with real-time data and insights, enabling them to identify inefficiencies, set consumption targets, and implement energy-saving measures.

  • Identifying Energy Inefficiencies: Energy monitoring provides real-time data on energy consumption patterns and usage trends. By closely monitoring this data, production managers can identify areas where energy is being wasted or used inefficiently. This can include pinpointing equipment malfunctions, process bottlenecks, or unnecessary energy consumption during idle periods. By identifying these inefficiencies, managers can take corrective actions to optimise energy consumption rates.

  • Setting Energy Consumption Targets: With energy monitoring data, production managers can establish realistic energy consumption targets for processes and production lines. Manufacturers can use these targets to identify deviations in actual energy usage and make necessary changes to bring consumption back in line with the targets. This approach ensures that consumption rates are optimised to meet operational requirements.

  • Implementing Energy-Saving Measures:  By analysing consumption patterns, managers can identify opportunities for equipment upgrades, process optimisations, or changes in operational procedures to reduce energy consumption. These measures can include using more energy-efficient equipment, implementing automation systems, or optimising production schedules to minimise energy waste.
