STE18-A is an STS Standard compliant, keypad type, automatically connection or disconnection three phase prepaid electricity meter.

Three-phase meters have many advantages over single-phase meters:
1. In terms of power generation, the three-phase alternator has larger capacity than the single-phase alternator of the same size;
2. In terms of transmission, if the same voltage will be the same size of power transmission to the same distance, the three-phase transmission line than the single-phase transmission line saves material;
3. In terms of electrical equipment, three-phase AC motor is simpler in structure, smaller in volume and better in operation than single-phase motor
