18 Dec 1987TL;DR: In this paper, a correction factor is determined by comparing the sum of the readings of individual sub-meters with the reading of the main electricity meter and the sub-meter readings are multiplied by this correction factor, that is to say are corrected.
Abstract: An electrical service installation has a main electricity meter (33), which is accommodated in a mains connection box, and a line protection circuit breaker and/or residual current device (20, 21, 22), which is assigned thereto, for in each case at least one sub-load (13). An additional, electronic power measurement device (12, 14; 23 to 28) is assigned to each line protection circuit breaker and/or residual current device (10; 20, 21, 22) assigned to a sub-load (13) or to each group of line protection circuit breakers or residual current devices assigned to a load (13). In consequence, cost-effective sub-meters can be provided which do not need calibration. A correction factor is determined by comparing the sum of the readings of the individual sub-meters with the reading of the main electricity meter and the sub-meter readings are multiplied by this correction factor, that is to say are corrected. This service installation is used especially where calibrated and expensive secondary electricity meters are uneconomic.

07 Apr 2003TL;DR: In this article, a power meter is designed to monitor the source of power to confirm the radiation source provides a desired dosage, and a current transformer is also associated with the power meter.
Abstract: A system and method are provided for monitoring and/or controlling a sterilization system. Briefly described, in architecture, the system can be implemented as follows. A current transformer is operatively associated with a source of power for a radiation source. A power meter is operatively associated with the source of power. The power meter is also operatively associated with the current transformer. The power meter is designed to monitor the source of power to confirm the radiation source provides a desired dosage.

TL;DR: The development of an IoT enabled smart energy meter capable of real time load management is explained and the real time energy monitoring is visualized using a mobile application.
Abstract: A smart energy meter provides real time power consumption data. This helps the consumer to manage their power requirement efficiently and economically. In a developing country like India, there is a rapid growth in the power sector. This paper explains the development of an IoT enabled smart energy meter capable of real time load management. The real time energy monitoring is visualized using a mobile application. The application also serves as a smart home controller where the user is capable of controlling the electrical appliances remotely or controlled based on events set by the user.

TL;DR: A study on the development of an Internet-of-Things (IoT) based residential power monitoring and protection system (RPMPS) that combines the role of an energy meter and the traditional distribution fused board, with the inter-operability, scalability and advanced remote real time monitoring and control functionalities.
Abstract: The need for fault detection and isolation of power supply from appliances is a vital component of safety in homes and residential facilities. There is a growing trend and motivation to optimize energy domestically and minimize the down time of power availability due to faults in homes and offices. This paper presents a study on the development of an Internet-of-Things (IoT) based residential power monitoring and protection system (RPMPS). The continuous power monitoring system was designed and hardware-implemented as a GPRS-enabled device, with Short Message Service (SMS) capabilities, and access to the internet for effective remote monitoring and real-time protection in the different sections of the dwelling. The system is capable of providing protection over electrical hazards, voltage surges, over loading, high temperatures and other faults on the residential distribution lines. Also, the system can detect electrical smoke, shuts down the system, and relay the message of the event remotely. The system combines the role of an energy meter and the traditional distribution fused board, with the inter-operability, scalability and advanced remote real time monitoring and control functionalities. The high-tech system serves as an easy-to-install upgrade to the basic electrical distribution board for fault detection of electrical wiring faults and protection. The meter in the device has the capacity to adequately measure and indicate the parameters of power supply to appliances, leading to more efficient utilization of electricity.
