Glow Wire Test: Resistance to Heat and Fire
The glow wire flammability test is used to simulate the effect of heat that may occur in malfunctioning electrical energy meters, such as when components are overloaded or glowing.
Basic Information about UL Standards
Underwriters Laboratories (since 2022 renamed to UL Solutions) created the UL standards as product safety requirements for the American market starting more than one century ago.
The Hidden Pitfalls of the Energy Transition
By transitioning to renewable energy sources such as wind, solar, and hydropower, we can reduce our greenhouse gas emissions and mitigate the impacts of climate change.
The Power Grid: Why a Smart Meter AMI System is the Way to Go
The grid is managed by utility companies, who have the responsibility of ensuring that the electricity generated is distributed to all customers in an efficient and reliable manner.
Virtual Power Plants and the Energy Transition
A Virtual Power Plant (VPP) is a network of distributed energy resources that are remotely connected and operated as one entity. The VPP’s role is to ensure a stable energy flow and system reliability while minimizing cost and emissions.
Re-energizing the Future: The Next German Smart Meter Rollout
The adoption of smart meters stagnated for years. The German government is now attempting a fresh start, a tried-and-true strategy when things in the digital world become stuck.
Smart Grid Evolution in 2023: The Future of Energy Management
The world is still in the transition phase to large scale integrated smart grids. One additional challenge is the smooth integration of renewable energy sources together with energy storage technologies.
What is a Power Conversion System PCS?
A power conversion system is a mono- or bidirectional converter that can control the charging and discharging of batteries, perform AC and DC conversions, and directly supply power to an AC load in the absence of a power grid.
Advanced Metering Infrastructure and Smart Grid
A smart grid is the logical consequence of AMI solutions and the result of an evolutionary process. It is necessary to test and gradually incorporate new controls, notably the SCADA components.
Benefits of Bidirectional Energy Meters
A bidirectional energy meter can record energy usage, monitor power generation, and estimate the cost of energy. The meter allows for more flexibility and information in electrical usage.
The Effects of Renewable Energy on Power Quality in the Grid
Power grid operators need to consider the total harmonic distortion. It has to be maintained as low as practicably possible. Higher power factor, lower peak currents, and more efficiency result from decreased THD in the grid.
Crest Factor for Voltage and Current
The crest factor can be used as additional indicator for the power quality in the grid. The impact on power transformers, circuit breakers and other elements like uninterrupted power supply (UPS) needs to be considered during the planning stage.
The Efficiency of Solar Power at High Elevation
Photovoltaic panels at a higher altitude are receiving more solar radiation compared to the sea level, resulting in more generation of electricity.
The Challenges Of Electrical Power Grid Restoration
If a grid is running very close to its maximum capacity and a major event happens, e.g. fire in a generator, a whole power plant goes offline. The other plants connected to the grid must start up in order to meet demand when that plant disconnects.
Renewable Energies: The Different Types
Renewable energy technologies are becoming more popular as the cost continues to fall. These technologies have the ability to cut emissions and supply sustainable energy, which are crucial not only for this generation, but also for a better future.
Power Grid Frequency: Why is it Important?
The grid frequency can be used to determine whether the network is in balance. If it drops below nominal, there is a higher demand than generation.
Distributed Energy Resources and Microgrid
Microgrids are used to provide power for remote or underserved communities, campuses, military bases, commercial and industrial facilities, and other critical infrastructure.
What is Residual Load?
The part of the electricity consumption that remains after deduction of the feed-ins by the two renewable energies wind and solar power is called residual load.

Please what causes the prepared credit to ran fast?
The credit deduction is based on your consumption. If you use less electrical energy, the meter runs slower.
My CL710K11 Single Phase AMR Prepaid Meter is blinking red light at “warning” sign indicator. What does this mean?
If there is no other indication on the display, it means that your credit is getting low.
Thank You! So much for a great blog and best of luck for the future,
I’ll be in touch.
Thank you for your interest. You can swipe down the page bottom and subscribe to our weekly newsletter.
Kindly how can I silence my meter even after dailing 812# still it will revive on its own and starts beeping its really annoying.
The beep can only switch off temporarily for just one minute.
The beep appears because there is an alarm, either low credit, or overload, or tamper.
You can silence your meter permanently after you solve the alarm.
I have a clou meter token and am just wondering how i can silence the beeping alarm that goes off when your are low on tokens. Its kinda annoying. Ypur help will be highly appreciated.
Steve, try code 812 on your UIU (user interface unit) and confirm by pressing the enter-button (blue or red). If it doesn’t work, please tell us the meter model type.
How can someone test reactive energy kvarh in a meter test bench?
If the energy meter has a function for measuring reactive energy, it must have a test output (a flashing diode) indicating the reactive consumption. This test output has a meter constant, indicated in e.g. pulses per kvarh. You set measurement mode in your test plan to reactive measurement and adjust the scanning heads in front of the reactive diode. All other procedure is the same like active accuracy test. The settings for reactive power is done inside the test bench and reference standard automatically.
which is the standard to be used for testing of for Reactive power in energy meter and what are the acceptable error margins?
The IEC 62053-23 is applicable for static meters for reactive energy (classes 2 and 3). The allowed errors for accuracy are given in the related tables. If you have a meter with reactive class 2, the allowed error is +/-2% for all balanced loads above 0.1 Ib and power-factor 1.
My CLOU (CL710K11) just shows zeros when I try to enquire balance or input new token, I think it is not communicating with the power source
The possible reason could be long communicate distance or the power cable quality,plsase use another socket and try again. if still doesn’t work,pls confirm whether the UIU address is right one( enter 1593570 plus the meter number to set the UIU address).
Where can I find the operational manual for clou meter, with series number CL710K11
Thank you for your message. The operation manual is for the power company or utility. End users get an introduction by the power company and a reference card with the user interface short codes. The configuration for each power company is different. If you are in doubt about a function, ask your power supplier.
My CL710K11 meter
Red light is lit next to the word “WIRING” and I noticed low power in house today. Any idea what could be the problem.
It indicates a poor communication between the user interface unit and the meter. One reason behind can be a very low supply voltage from the grid.
