Based on GE’s proven controller platform with tens of thousands of units installed globally, the Multilin Voltage Regulator Controller underwent extensive Accelerated Life Testing (ALT) and Highly Accelerated Life Testing (HALT) to validate accurate functionality under specified conditions and to ensure accurate performance in extreme operating conditions and harsh environments.
Mode of Operation
To provide optimal application flexibility, the Multilin Voltage Regulator Controller offers two modes or methods of operation in which the device can be implemented to control the voltage regulator: a) Manual Mode (Local Control or Remote Control). b) Automatic Mode
Manual Mode – Local Control
In this mode, it is possible to Raise or Lower the tap locally from the Push buttons that are available on the front panel of the Multilin Voltage Regulator Controller. For added operational reliability and operator safety, inhibit functions configured in the unit continue to operate as defined.
Manual Mode – Remote Control
In this mode, the commands for Tap Raise and Lower are received from SCADA or the Integrated Volt/VAR systems via communications. This communications channel can be provided via optional radio or cellular communications.
Key Features to Optimize Voltage Regulation:
In automatic mode, the Multilin Voltage Regulator Controller compares the measured voltage to the set voltage level, and if the difference exceeds the set bandwidth (voltage limits), the Multilin Voltage Regulator Controller issues a Raise or Lower tap commands to maintain the desired voltage levels.
