Abstract: The troubleshooting of wrong wiring of three-phase three wire electric energy metering has always been a difficult point for electric energy metering workers.Aiming at the problems of high cost, complex operation and difficult popularization of current training equipment, this paper studies a parallel high-voltage three-phase three wire electric energy metering wiring type simulation training device.The manufacturing cost is low, the operation is simple, and the work station is easy to expand.It can simulate the common connection type of three-phase three wire electric energy metering.It can be used for the training and evaluation of power consumption inspection, power metering operation and maintenance and other types of work, greatly reducing the training cost.
