The role of instrument Transformers (Current & Voltage CTs & PTs)
Overview
Credit: 4 technical hours
Other than theoretical, simple power calculations in a system, engineers and technologists may not be familiar with the standards and practical installation that are required in today’s power billing. This course closes that gap and introduces how utilities deal with measuring power and energy, developing two-wire Single-Phase, three-Wire Single-Phase, 3 Phase 4 Wire ("Y" Connected) and 3 Phase 3 Wire (Delta Connected) Metering installation Standards.
This course concentrates on the electricity meter, electric meter, electrical meter, energy meter, or kilowatt-hour meter which is a device that measures the amount of electric energy consumed by a residence, a business, or an electrically powered device.
From the Electric utility perspective, electric meters installed at customers' premises for billing and monitoring purposes are examined. The typical calibrated in billing units are developed, the most common one being the kilowatt-hour (kWh) and how they are read once each billing period. Electric meter or energy meter measurements and the total power consumed over a time interval are examined. If desired, some meters may measure demand, the maximum use of power in some interval. "Time of use" metering allows electric rates to be changed during a day, to record usage during peak high-cost periods and off-peak, lower-cost, periods. Single-phase and three-phase metering measurements are also covered.
