Application

  • It is an electricity meter installed in consumer premise which has an inbuilt disconnecting relay. The consumer buys electricity in advance by paying at any of the vending office or he can do an online purchase. The purchased electricity amount is transferred to meter through a numeric code. The amount in the meter is deducted as per the usage and tariff charges. Once the amount is exhausted the meter provides an alarm to consumer on its in-home display and further on zero balance it automatically disconnects the supply. The consumer can reconnect himself by buying more electricity and recharging the meter. This system completely caters to the consumer convenience and never disconnects the supply outside office hours.
