Introduction of High-Power Electric Testing Lab: Two 850-MW Electrical Short-circuit Test Generators that Allow Testing up to 100 kA RMS Symmetrical and Up to 230 kV

#foothill #pes #energy #electric #power #generation

S&C's corporate headquarters in Chicago is home to one of the world's leading electrical testing laboratories. Our 20,000-square-foot Nicholas J. Conrad Laboratories (NJC) is well equipped to meet the rigorous testing requirements for electrical equipment; it has two 850-megawatt electrical short-circuit test generators that allow testing up to 100 kA rms symmetrical and up to 115,000 volts. This presentation will focus on the NJC Laboratories High Power Lab Generators, including their design, operation, protection, controls and personnel required to operate them for high power electrical testing.

Kaleb Spencer of S&C Electric Company, NJC Laboratories, USA


Mr. Kaleb Spencer


Kaleb earned a B.S. in Electrical Engineering with a focus on Power Systems and Microgrids from Washington State University while maintaining the position of VP of the IEEE club on campus. Kaleb interned for Lewis County PUD, developing a standard for and beginning the first system-wide coordination study of that utility. He also was a Co-Op for Cowlitz County PUD and an intern for Brown and Kysar Inc., a consulting firm specializing in serving smaller PUDs and Co-ops; this led to many interesting challenges and unique opportunities. In 2019, upon graduation, Kaleb accepted an offer from S&C based on being a recipient of the IEEE PES John Estey Scholar Award. He began work in the Power System Solutions Group as part of the Protection and Controls team, contributing to projects such as Longdraw, Bluestone, and Lost Hills solar substations. He then moved on in 2020 to work in the Technology, Breakthrough, and Innovation (TBI) Group on the Vacuum Interrupter Team and the Interrupting Systems team. His time in TBI yielded several Invention Disclosures and developed a strong interest in the NJC Labs, as the projects often made use of these labs. Kaleb then transferred to the NJC Lab Team in 2022 as a Test engineer working on projects including Generator protection, a new Time Current Coordination (TCC) system, as well as becoming the zone leader of the Lab Extension.
