  • Patent number: 7269574
    Abstract: In order to spread a transformer having energy saving and environmental effects widely and quickly, a method for supporting received orders of a transformer is provided. In the method, a first response including a customer's desired inquiry relating to an installation date of a measuring circuit is issued from a sales department to a customer who accessed a web site of the sales department. A second response including the installation date of the measuring circuit is issued from a measurement department in charge of measurement of the transformer. Since cooperative communication is achieved between the sales department and the measurement department in charge of the transformer measurement, the system can quickly cope with the customer who accessed the web site of the sales department and a social demand of early realization of energy saving and CO2 reduction can be realized with highly excellent effects.
