Research On Microcomputer Fault Circuit Selection Adaptation To Digital Optical-Electronic Transformer

Potential/current transformer is the devices providing signals for power quality and relay protection, whose precision and reliability contact with safety and economy operation tightly. With the following increasing and the heightening, traditional electric-magnetism transformer can't satisfy the need of power system to automation and digital-network. The new transformer is looked for, one of which is called optical-electronic transformer, whose function is prime and research on which gets along quickly. Through 30 years work, optical-electronic transformers have operation in power system for test. At the same time, optical-electronic transformers will bring technology revolution on design, measurement, protection, control in power system.Fault circuit selection hasn't been solved effectively all the while while single phase-grounded fault occurred in non-solid grounded system. The causation represents on two aspects: first, traditional electric-magnetism transformer can't suffice measurement and protection. On account of the...
