Abstract


The voltage transformer return route’s secondary voltage drop test is a periodic test, its goal is the testing voltage mutual inductor’s secondary voltage and the electrical energy meter voltage terminal difference of voltage whether to surpass the regulations stipulation the scope, thus safeguards the power plant the economic interest, also guarantees between the power factory and electrical net’s fair deal.This article proposed that verifies secondary voltage drop based on the NRF905 wireless communication module the ideas, to the wireless NRF905 verify unit, the installment hard-ware design is relatively quite simple, but this article key point lies in software design. To the wireless communication, verify unit’s antijamming ability is very important, in the topic NRF905 verify unit has antijamming ability, mainly emphasizes in here in the survey in the sampling process antijamming method and the course of communications antijamming method, and carries on the test comparison on the spot to the NRF905 verify unit and the tradition verify unit in the laboratory.To conducts the research based on the wireless technology’s secondary voltage drop test, gives several kind of wireless verification technologies the field test data, and carries on the contrast with the tradition test method’s test data, analyzes each verification method systematically the characteristic. Has the good guiding sense to the electrical energy measuring system’s accuracy.
