Wholesale DC Reference Standard Meter is a high accuracy class 0.02 DC power and energy measuring instrument, widely used in electric power, industrial and military industry, metrology, scientific research institutes and other DC measurement fields or lab. It is mainly used for verification and calibration of DC voltage source, current source, power source or assessment of DC electric energy metering device with ripple test function.
The SMOG also contains new requirements for demand response resources with capacity and regulation product categories, adding a requirement to provide advanced notification of one day maximum to a capacity resource before the product category will be required to participate in organized wholesale electricity markets; setting an EPS telemetering interval of six seconds for products in the reserve and regulation service product categories; establishing a deadline for submitting meter data reports (103 days for the energy and capacity product categories and 55 days for the regulation product category); and providing a maximum adjustment window for baseline type-I and baseline type-II performance evaluation types. These changes build upon existing PJM Interconnection, L.L.C. and ISO New England Inc. manuals, the Federal Energy Management Program (FEMP) measurement and verification standards, and several state protocols.
A DC reference standard meter is an instrument that is used for measuring the accuracy of direct current (DC) electrical signals. It is a widely used tool in the electrical and electronic industries for testing and calibrating a variety of electronic instruments and equipment.
A DC reference standard meter is designed to provide accurate and stable readings of DC voltage, current, resistance, and power. It is used as a reference for calibrating other measuring instruments, such as multimeters, voltmeters, current meters, and wattmeters.
The reference standard meter consists of a precision voltage or current source, a precision resistance, and a digital display or analog meter for indicating the measured values. The voltage source is used to produce precise and stable DC voltages, while the current source is used for generating precise and stable DC currents.
The precision resistance is used to calibrate the resistance measurement range of other instruments. It is also used for checking the accuracy of resistance measurements of resistors and other components. The resistance is typically made of high-quality materials, such as Nickle-Chromium, and is designed to provide high accuracy and stability over a wide range of temperatures.
