About the 8271-468

The standard commercial functionality of the Generator Loading Control unit 8271-468 is programmed into the unit. This allows the unit to control user-selected adjustments of the electrical load assumed by the Genset. Operating and adjusting the 8271-468 to the desired specifications, depend largely on the unit’s use of a power system.

It can use an isolated power system, or a local system, which is paralleled to an infinite bus. When in an isolated system, the 8271-468 Generator Loading Control is used with each load sharing and speed control. It is connected to the paralleled lines from both of them and can detect the generator’s load. This unit’s output is designed to bias the line voltage to assume control over a fraction of the total system load. Twelve wire terminals are appropriately labeled by the manufacturer for their usage. If paralleling to an infinite bus, measure the voltage at the load signal test jacks of the Generator Loading Control while the unit is fully loaded.

In isochronous paralleling applications, the Generator Loading Control part number 8271-468 regulates the power while the utility maintains frequency. An advantage of this type of control system over the standard droop operation of paralleling is that on parting from the utility, the now-isolated bus is automatically under isochronous speed control without the operator having to readjust the speed settings.
