Reliability Verification of Single-phase Earth Short-circuit Protection in Super High-rise Buildings
This paper discusses the necessity of automatic disconnection of supply for verification of protection against indirect contact calculates the single-phase earth short-circuit current of typical distribution circuits in super high-rise buildings and checks the sensitivity of circuit breakers,and provides some suggestions on the selection of circuit breakers and cables for super high-rise buildings through comparative analysis of measures to improve sensitivity.
