CAPACITOR SWITCH

Product catalog summary

Introduction
The document discusses a vacuum-based capacitor switch designed for 11 kV pole-mounted applications, manufactured by Crompton Greaves Ltd. It addresses the challenges of varying line currents in distribution networks and the benefits of using switched capacitors to improve power factor, reduce transformer load, save energy, and enhance voltage regulation.

SmartVAR Controller Features
The SmartVAR3 controller is designed for single-step mechanically switched capacitors (MSC) and includes features such as current control, delay logic to prevent frequent switching, under and over-voltage protection, low load protection, and both auto and manual control modes. It also provides online voltage and current display and is password protected.
