DESIGN OF AN INTELLIGENT NITROGEN INJECTION SYSTEM FOR FIRE SAFTEY OF POWER TRANSFORMER

Abstract

Fire hazards occurring at power transformers and interconnecting transformer installations are the matter of serious concern. These may lead into serious consequences such as fatal/non-fatal accidents and loss of valuable assets. One Power transformer costs to Rs. 4 Crores/40 Million Dollars approximately. Moreover such types of incidences may cause fatal or non-fatal accidents to human being or stray animals. On number of occasions there is a sudden blasting of porcelain bushings . The pieces of porcelain are scattered in the switchyard with a velocity of bullet and cause damage to nearby equipments in the switchyard. The Nitrogen injection system is the traditional method of quenching fire hazards occurring at transformer installations . It is desired that reporting of such occurrences should be as quick as possible. This paper suggests a novice method for communication of such occurrences based on client-server interaction by connecting it to the traditional Nitrogen injection system. The proposed communication system is based on the notion of client server communication. Server is the process that is offering some service on receipt of request from the client. Client is the process that requests server to provide service. The socket programming based technique is found to be an effective tool for quick communication of such incidences on CMS client , smart phones and ESR terminals. It is possible to implement the proposed system on existing client-server network used for transmission of ABT data from substation/consumer installation to the Central Monitoring System. The Java embedded system can be developed as a dedicated hardware for proposed Client –server Association.
