STS energy meter

The gradual increase in Africa's electricity infrastructure has led to a gradual increase in the demand for electricity. However the difficulty of collecting and paying bills has been a problem for both electricity sales and customers. To solve this problem, the STS association was established in 1993, initiated by Eskom, to successfully address the compatibility between meters and vending systems of different suppliers. There was also a need to ensure adequate system security to prevent fraud. the STS project was quite successful in enabling vending systems from different manufacturers to offer compatible token/credit transfers to any STS-compliant meter (from many manufacturers). The development, manufacture and sale of prepaid meters in Africa revolves around the STS association, and Yongtailong, a long-standing STS member for over 10 years, has a wide range of single pahse and three phase meters in many types and with different features.
