Anti Theft Power Smart Metering System

PT PLN (Persero) which has more 89,1 million customer plays important role to distribute electricity to people. Even though PT PLN still has many problems on of which is losses energy in distribution system. Distribution system came from substation to 20KV line to distribution substation and then to kWh meter. Distribution losses can happen in two that is technical losses and non-technical losses. One of many reasons is happened in kWh meter. In PT PLN has two system kWh meter that is postpaid and prepaid. Postpaid still use conventional system that has to be reading physically by custodian and prepaid system use buying token before we use kWh meter. Postpaid system can't detect theft electricity from customer just using conventional system. With microcontroller, IC power energy watt meter and GSM GPRS module we can build system that detect theft electricity and avoid non-technical distribution losses. The IC power energy meter STPM10 can calculate highly accurately voltage, current, active power, reactive power and frequency of line power. The module can send data to local server in distribution substation and analyze usage of distribution substation deviation with amount of usage kWh in the same distribution system.
