However these installations are not equipped with smart meters and other functionalities of a smart metering system. There are many different types of meters installed and different software has to be used to remote read the meters. After reading the meters, meter readings have to be manually entered into the bulk supply billing system for the preparation of bills. The present system has facility only to remote read the meter. There are many added befits to CEB as well as customers when a fully pledged smart bulk metering system is installed for the CEB including a smart bulk meter, communication network and meter data management system. CEB should finance the above program and GPRD/3G/4G/Fiber technology could be used to communicate between the smart meter and the Meter Data Management System.#23AMI Project for Bulk Supplies in CEB Sub Project Name Description Project Cost (USD Million) Funding Duration AMI Project for AMI Project for 2.0 CEB 2019 - 2020 Bulk Supply Customers of Bulk Supply Customers of the CEB the CEB#24AMI Project for Power Quality Management With smart meters in the network, the utility will be capable of measuring specific aspects such as power factors and voltages in near real time. This will enable the utility to take appropriate actions to enhance the power quality and reliability. In order to achieve above it is recommended to install a smart meters with AMI infrastructure and functionalities to all LV feeder ends (about 100000 in numbers) of CEB and to use AMI system of the utility to measure power quality parameters in near real time. This will enhance power quality, meet regulatory requirements and for operation and planning of the distribution network. This should be done using CEB finances.#25AMI for Distribution Transformer Monitoring System Remote monitoring and control of distribution transformers will prevent overloading, phase imbalance and burn outs. This will transform into huge financial savings taking into account the high technical losses that occur in the system owing to phase imbalance one phase gets overloaded while other two phases are low on load. - With monitoring systems in place the loads can be distributed to remove such imbalances on transformers. Also this will facilitate real-time energy auditing of each feeders.
