Grouped Switching Reactor Set GL-1

The GL-1 reactor set compensates capacitive reactive power, improving power factor and voltage quality in long cable lines and high-demand projects. It addresses voltage distortion, power factor degradation, and network loss, operating continuously in both indoor and outdoor substations for reliable power distribution.

Description

GL-1 Grouped Switching Reactor Set Features

Communication Interface
Standard industrial RS/485 communication interface.
Switching Mechanism
Uses permanent magnet vacuum circuit breakers or long-life vacuum contactors to automatically select and switch reactors based on reactive power demand, ensuring smooth switching without oscillations.
Manual/Automatic Control
In automatic mode, reactors are switched on when the power factor is below 0.9 and switched off when it exceeds 0.95. No action is taken between 0.9 and 0.95.
Optimized Reactor Grouping
Reactor grouping allows for efficient reactive power control with fewer reactor units. For instance, three reactors can provide multiple reactive power values, reducing cost and space.
