Main features of LPWAN Technologies Low power RF technology Low current consumption, therefore long battery life Wide area coverage, compared with other technologies like Bluetooth Wifi. Lower cost than mobile networks, such as 5G Enable wireless connectivity of remote ‘field’ sensors to internet gateway devices. A key component in the internet of things. Suitable for […]
Single Phase Transformers are most commonly ‘step-down’ types.
This means that the voltage that comes out is less than the voltage going into the transformer.
Condition Monitoring Smart factories improve automation and efficiency compared to traditional factories. Efficiency is increased both through process decisions being made without human intervention. Efficiency is also increased by using sensor data to monitor the condition of machinery, such as three-phase induction motors. Monitoring of induction motors, can include vibration sensors, which monitor the condition […]
Radio Waves What does your microwave oven have in common with your WIFI connection? The short answer is radio waves. A microwave oven operates by bombarding the food with high frequency radio waves. A device called a Magnetron bombards focused electromagnetic waves at the food inside the microwave Oven. This works by heating the molecules […]
Preventative Maintenance Preventive maintenance programmes are the key to reliable, long-life operation of electric motors.Whilst AC Induction Motors are particularly reliable in service, almost all electrical equipment requires periodic planned inspection and maintenance. Planned preventative maintenance ensures electrical motors, and starters are kept in good working condition at all times. This is critical for businesses […]
Performance of the Electric Vehicle conversion is my next consideration in the electric Alfa GTV project. The standard 2 litre ‘twin spark’ engine in the factory standard Alfa GTV, propels the car to sixty miles and hour in just over 8 seconds. Increasing performance is one of my objectives for the project, in addition to […]
Railway Global System for Mobile Communications GSM-R The railway Global System for Mobile Communications is also known as GSM-R & ‘GSM-Railway’.GSM-R Global System for Mobile Communications) is an international standard, covering railway communications.It is a sub-system of the European Rail Traffic Management System, or ERTMS .ERTMS is used for communication between trains and the railway […]
Induction Motor Servicing. Induction motors are used widely in factories and on ships. They are very reliable machines, but faults can develop over time. That is why you need Induction motor servicing to be carried out. Potential faults include burnt out Stator windings, worn bearings, and water damage which causes low insulation resistance. This article […]
