RADIAN Timeline


In 1985 Radian Research began production of its first product, the RADIAN Metronic RM-10 Portable Watthour Standard. The RM-10 provided specific innovative features, developed by Glenn Mayfield, which improved accuracy, enhanced testing efficiency and provided greater safety. The Radian RM-10 was the first energy metering instrument in the world to provide a wide range auxiliary power input AND an auto-ranging voltage input. These innovations by Glenn Mayfield dramatically changed the technology of energy meters and reference standards made by all manufacturers of such products around the world. Auto-ranging inputs for current (0 to 50 amps), voltage (60 to 600 volts) and auxiliary power (80 to 600 volts) made it impossible to damage the unit by applying a signal to the wrong tap. A true watthour display with a Kh of 1 on all ranges allowed for a much simpler energy meter error calculation. Remote digital display gating eliminated the need for switching the potential while further enhancing accuracy. With its high accuracy, innovative features and a weight of only 5.5 pounds, the RM-10 soon became the number one selling watthour standard in North America.

In 1986 Radian Research introduced its first primary watthour standard, the RM-11. The RM-11 was the most accurate, precise and stable self-contained primary watthour reference standard manufactured in the world. The RM-11 provided many of the same innovative features which were previously introduced with the RM-10. The RM-11 was so accurate and stable that many laboratories in the US began transferring the watthour directly to NIST instead of using traditional DC to AC transfer methods.

From 1986 to 1990 RADIAN added various meter testing accessories to its product line. These accessories assisted in the automation of testing induction and electronic energy billing meters. During this same time Radian Research was investing several million dollars into the research and development of an automated AC laboratory reference system based on its legendary Syntron signal sourcing technology. The result was the RS-703A Syntron Automated Calibration System with an accuracy of +/- 0.005% +/- traceability uncertainty. The RADIAN RS-703A soon became revered and respected as the most accurate, functionally advanced AC electric energy calibration system in the world.

By 1993 Radian had experienced significant growth requiring it to purchase land and have a 22000 square feet custom facility built. This facility became the Corporate Headquarters for Radian Research and housed all aspects of the business operation.

From 1993 to 2003 Radian continued to introduce new technologies and solutions to their portfolio. The most profound of these was the RADIAN Dytronic RD Series of single-phase and three-phase multifunction reference standards. RD standards featured RADIAN designed Analog to Digital Converters optimized for power and energy measurement. RD standards added profound new capabilities including simultaneous measurement, extensive harmonics measurement and built in comparator options in becoming the replacement for the RM series of energy reference standards.

In 2005 Radian Research purchased Utility Test Equipment Company (UTEC). The acquisition of UTEC enabled Radian to significantly expand its product offering to the electric utility industry by providing turnkey field test systems for energy meters and current transformers as well as individual equipment pieces that allow customers ultimate flexibility in meeting their testing and calibration requirements.

In 2008 Radian expanded its facility to 30,000 square feet with a new Research and Development Laboratory coupled with new offices and break room. The corporation also went through a restructuring of its ownership into an ESOP and 100% Employee Owned.

In 2009 Radian Research, Inc. was recognized as one of the 50 Top Companies to Watch in the State of Indiana. This is a prestigious award given to those companies that have a high growth of revenue and accelerated job creation. The company also started shipping its next generation of Syntron Automated Laboratory Calibration Systems, the RS-933 which featured expanded current sourcing capabilities.

In 2011 Radian Research acquired 100% of Watthour Engineering Company (WECO) stock to combine the companies under one ESOP umbrella. The combination of RADIAN and WECO created the world's largest and most technologically innovative provider of energy reference standards, advanced energy meter testing systems and automated laboratory calibration systems. Radian Research now operates out of two facilities ... a 40,000 square feet facility in Lafayette, Indiana and a 25,000 square feet facility in Pearl, Mississippi.
