Which of the following statements are correct? (i) Advanced metering infrastructure (AMI) is typically more automated and allows real- time, on-demand interrogations with metering endpoints. (ii) An Automated Meter Reading (AMR) device only communicates from the customer to the energy supplier. (iii) AMR meters only provide kWh information and possible peak kW demand for the month.
Advanced metering infrastructure (AMI) is an integrated system of smart meters, communications networks, and data management systems that enables two-way communication between utilities and customers. The goal of an AMI is to: Provides utility companies with real-time data about power consumption and allow customers to make informed choices about energy usage based on the price at the time of use.
Die-electric test on Circuit breaker: These tests are performed to check power frequency and impulse voltage withstand capacity. Power frequency tests are kept on a new circuit breaker, the test voltage changes with a circuit breaker rated voltage. In impulse tests, impulse voltage of particular value is employed to the breaker.
