The DWK is a new type of pole-mounting high-voltage var (reactive power) compensators. It consists of current transformers, potential transformers, controller, vacuum contactor and shunt capacitors. The DWK features high level automation, small size, light weight, and easy installation. It is mostly applied to 6kV and 10kV distribution lines, switching capacitors automatically on multiple modes such as voltage, time, voltage/time, voltage/var, and power factor. Integrating static and dynamic compensation and multi-step switching has realized more precise reactive power compensation on HV distribution lines, thus greatly raising the power factors in the system and reducing power loss on distribution transformers and lines. The DWK is a powerful instrument for enhancing power delivery efficiency and improving user power quality.

Features
- Intelligent capacitor switching
- Intelligent capacitor switching controller is built on industrial grade chips, functioning normally when the ambient temperature varies between －40℃ to 45℃.
- Five-mode control
- Five-mode control enables user to flexibly select the best mode to minimize power loss.
- Complete protections
- Complete protections: capacitor overcurrent quick break, overcurrent protection, overvoltage protection, undervoltage protection, delay, incomplete-phase operation protection, and limit on the number of capacitor switching per day.
- RS-232 communication port
- RS-232 communication port enables remote readout and transfer of real-time data and hourly data, remote switching of capacitors, and via GPRS or CDMA, can realize wireless telecommunications.
