How to increase timing accuracy: Stephen Boronkay presents an application that replaces an obsolete high electrical power test controller

摘要

THE challenge posed was to replace an obsolete high electrical power test controller with a solution that offers easier maintenance, more features, and greater flexibility. The solution developed used NI CompactRIO, LabVIEW and digital I/O to coordinate test sequencing for superior timing accuracy combined with the ability to interface with existing hardware. The existing program controllers at the client site were in-house manufactured timing units that coordinated test sequence events required for high-power testing procedures of electric utility distribution equipment. The systems consisted of custom-designed hardware controlled by a DOS computer that became increasingly difficult to service.
