REQUIREMENTS DOCUMENT

Title: Electrical Calibration

Requesting Lab: Engineering Laboratory

I. BACKGROUND INFORMATION

The Mechanical Systems & Controls Group at the National Institute of Standards and

Technology (NIST) expands the scientific knowledge of building operation and integration with the smart electric grid. The group’s focus is to improve energy efficiency of building equipment through measurement, control strategies, and technical insight related to grid stability, power quality, integration of distributed renewable energy resources, and provision of ancillary services. The research activities include power system monitoring, simulation, and data analysis.

To fulfill its mission, the Mechanical Systems & Controls Group requires calibration equipment to characterize the electrical performances of voltage and current sensors, and power meters. The calibration equipment will be used to quantify the measurement uncertainty, frequency response, and gain of various voltage and current sensors, and power meters. The calibration equipment purchase supports the objectives of the Electrical Performance of Grid-Interactive Efficient

Buildings (EPGEB) and collaboration work with the Office of Facility and Property

Management. A key component of measurement science to support EPGEB is collecting high-quality data such as high-frequency voltage and current waveforms, and electrical power and energy consumption data. Collecting high-quality data needs accurate instrumentations that require frequent calibration and spot checking. The impact of this invested equipment is not limited to the EPGEB project, it will allow other researchers in Division 732 to calibrate various electrical measurement equipment to advance their project requirements.

Purpose/Objective:

The objective of the requirement is to calibrate various electrical measurement instruments.

More specifically, the objective is to quantify the measurement uncertainty, frequency response, and gain of electrical measurement equipment.
