This paper analysed the characteristic of Power consumption at many type of Inverter controlled Elevator. Especially, this paper proposed the standard value of full load currents. For this propose, it was classified by the passenger capacity and manufacture company. As a result, it is found that (i) the value is between -3[A] and 7[A] in case of elevator. That means the full load currents was smaller than the standard value of conventional operation type (ii) the value is between 0.5[kVA] and 3[kVA] in case of Power transformer. That means the transformer capacity was smaller than the standard value of conventional operation type. it was classified by the passenger capacity at inverter controlled elevator in apartment Also, to guarantee the operation stop of inverter controlled elevator, this paper proposed the redundancy method of electrical installations. the redundancy method is (i) 2 line service system and (ii) 2 distribution line system.
