Electrical products and equipment are typically designed to operate within a limited voltage band. Poorly regulated voltage often results in adverse and unacceptable equipment performance. Problems that can occur include damage electronics, inefficient operation of motors, dim light bulbs, and a myriad of other issues.
Heavy electrical loads and long distribution lines drag down system voltages. Voltage regulators enable utilities to maintain voltage levels within acceptable ranges giving utility customers the assurance that electrical equipment will operate properly. Voltage regulators provide 32 steps, 5/8ths percent per step, for a total regulation of +/- 10% of system voltage.
The latest voltage regulator technology provides important advantages over traditional designs:
- Electronic controls with advance features supporting smart-grid technology and SCADA communications
- Multi-phase control operating two or three regulators with a single controller
- Quik-Drive tap changers providing operation through 32 steps in under 10 seconds improving power quality by providing faster recovery from large voltage swings
- Tap changers with vacuum technology, higher load ratings, and reduce maintenance requirements
