Laboratory AC Metrology

Radian offers many key components for setting up or upgrading an electric standards or meter laboratory.

Radian Laboratory Calibration Systems can provide functionality to essentially serve as an AC standards laboratory with no other instruments needed. While these calibration systems can serve as primary sourcing standards for numerous electric measurement parameters, the RD-22 Primary Transfer Standard provides a more traditional primary sensing standard. The RD-22 is the most accurate sensing standard that Radian offers, and is one of the most accurate standards in the world. The RD-22 can either be used stand-alone with third party voltage and current sources, or as the primary reference to RS-933 Power & Energy Automated Calibration systems to provide the ultimate AC standards laboratory. In this scenario, the RD-22 can be the primary reference standard while the RS-933 serves as a secondary standard. The RD-22 can also bridge the gap between your fundamental DC references for voltage, resistance and time by offering DC to AC accuracy transfer abilities. DC references are available from companies like Fluke, Guildline and Arbiter Systems.

Secondary Standards are used for testing working or field standards. The RD-21 Portable Reference Standard serves as the definitive secondary standard. It can be used to test field standards or standards inside of meter test boards. The RD-21 can also be used as primary watthour reference standards. A set of three RD-21 standards is typically used in this primary standard application.

Radian Calibration Lab Services provide a variety of options for standards laboratories to maintain NIST traceability for their primary and secondary standards. Radian's calibration lab maintains NIST traceability for numerous electric energy parameters including Watthours, AC Volts, AC Amps, AC Watts and time.
