“…Furthermore, reference [14] also emphasizes the significance of monitoring, controlling, and supervising of the household appliances along with the appropriate communication protocols that ensures the reliability of the data collection with the help of advanced algorithms and sampling tools. Another similar concept of measuring individual loads but in a three-phase measuring system is presented in [15], where the device logs the data onto the SD card. The PIC is interfaced with isolated current and voltage sensors for measurement.…”

With the significant increase in energy demands in the last decade, the issues of unnecessary energy usage have increased rapidly. Therefore, there is an immediate need to provide a cheap and easily accessible monitoring tool for the energy consumed by an appliance used in homes and industries. Instead of monitoring the total power consumption of the houses and/or industries, it is useful to monitor the power consumption of the individual appliance, which in turn, helps in saving the overall energy usage and thereby makes it cost-effective. This paper presents a cost-efficient design and implementation of a monitoring system that can precisely measure the current and voltage of each appliance. The design provides tracking of device activity in a real-time environment for the industries and helps in adopting to the green initiative. The design comprises of Arduino based micro-controller and Raspberry Pi, that performs precise measurements of current and voltage of the device, followed by measuring the power consumed by the device. This paper presents two different system designs, one for the single-phase measurements and the other for the DC measurements. The single-phase measurement device comprises of 10-bit ADC whereas, the 24 V DC measurement device comprises of a 12-bit ADC, which provides higher measurement accuracy compared to other systems available in the market. The implemented design uses the EmonCMS web application to accumulate and envision the monitored data. It provides a flexible and user-friendly solution to monitor the measured data easily on any android or iOS devices.

Industry 4.0 is the term for automation and transparency of data using the latest technology. This concept can be applied in several aspects of life besides the manufacturing industry. The Boarding house is a type of industry that has been thrived in D.I. Yogyakarta. It became a place of residence for students and workers in urban areas. As one type of business, boarding houses need a good management system for the best service and run efficiently. At this time the boarding house is still managed traditionally. Along with the development of IoT (Internet of Things) technology, several problems and its challenges can be solved with this technology. 5 types of sensors are used to realize this research. The sensor sends data and then the information is processed in a software application. This research uses a mobile application and integrates the sensors to monitor and control boarding rooms. This research can be used to face the new normal challenges, using the latest technology. The challenge of contactless process, energy efficiency, open information, and data can be well prepared by boarding house owners. The proposed system is predicted to save electricity costs for each bedroom by approximately 38% and also affect the saving of electricity bill payments by managers.

Assessment of the energy efficiency estimation methods on induction motors considering real-time monitoring

Different methods have been developed to estimate the energy efficiency of induction motors. The accuracy of these methods vary with the load factor, the unbalanced voltage (UV) and harmonics. The feasibility of these methods for efficiency estimation in real-time were theoretically and experimentally assessed during the operation under different operational conditions (i.e. balanced sinusoidal voltage (BSV), harmonics, UV and harmonics with UV). Results show that for load factors over 80%, the air-gap method is applicable under any condition, while the slip method is only applicable under BSV or balanced harmonic voltage. Moreover, for load factors over 40%, the nameplate method is applicable under BSV. Other methods result in errors over 8% and optimization methods are not applicable for real-time monitoring. Electric systems generally operates with some degree of UV and harmonics, while induction motors mostly operate with load factors below 60%, limiting the use of these methods for real-time measurement.
