Measurements of electricity are of great importance in our daily lives following the discovery and utilization of electricity in a variety of applications such as lighting and power generation. These measurements are among the important metrological applications that have a wide impact on residential, industrial, military, health, and civil sectors. To meet these diverse needs, the administration provides comprehensive calibration services in the Kingdom of Saudi Arabia in the fields of services and production. The administration consists of four main laboratories: Voltage Laboratory, Resistance Laboratory, Power and Energy Laboratory, and Electromagnetic Laboratory.
The Voltage Laboratory is an essential part of the Electrical Measurements Management at the National Center for Measurement and Calibration. The laboratory is responsible for establishing and maintaining standards for measuring both direct and alternating voltage, with accreditation to the electrical current unit (ampere), and disseminating them to all national entities and other calibration laboratories that measure voltage and current in industrial and service sectors. The laboratory provides calibration services for all relevant devices, including voltage and current sources and meters, using high-precision reference devices such as voltage reference cells, transformers, and DC and AC current meters. The laboratory has the capabilities and resources necessary to achieve the highest levels of accuracy in measurements, as follows:
