Product descriptions from the supplier
IntelliCap 2000 Automatic Capacitor Controls are specifically designed to control pole-mounted and pad-mounted switched capacitor banks in electric distribution systems to regulate reactive power or line voltage. These reliable, easy-to-use, microprocessorbased controls normally operate autonomously based on the control strategy selected.
With a one-way communication device installed, an IntelliCap 2000 control can also operate in response to switching commands from SCADA or other centralized control. With a two-way communication device installed, local status information and feeder data are additionally available remotely. Remote configuration also is possible.
IntelliCap 2000 controls are superior to other two-way communicating capacitor controls, which only operate in response to centralized control commands based on measurements at the substation. With the normal stand-alone operation of IntelliCap 2000 controls:
- A communication problem won’t compromise VAR support.
- A problem at one capacitor bank won’t affect other capacitor banks.
- Multiple contingencies are handled automatically.
- System changes and expansion don’t require extensive reprogramming.
Provide a Full Range of Automatic Functions
IntelliCap 2000 controls offer a wide range of software-selectable functions, including:
- Voltage, time, temperature, time-biased voltage, and time-biased temperature control strategies (VAR and current control strategies are optionally available.)
- Voltage/temperature and SCADA override strategies (When enabled, the control returns to its regular control strategy after receiving a SCADA command.)
- Automatic calculation of voltage change (and kvar change, if applicable) due to capacitor bank switching
- Automatic adjustment for daylight savings time and holidays
- A daily limit on automatic switching operations
Undervoltage and overvoltage protection Neutral input sensing is optionally available and can lock out the capacitor bank if blown fuses or stuck switch poles are detected.
The main function is to adjust reactive power. When the reactive power is insufficient in the power grid, the switch will put the capacitor in to compensate the reactive power, improve the power factor, improve the power quality, and reduce the line loss. When the reactive power is in excess, the capacitor can be removed.
This device can connect to SCADA System and DMS, and you can connect the terminal to the server according to your local network conditions. This terminal supports CDMA (3G)/LTE (4G)/ NR（5G）, ETH, fiber optic and other ways to access the network. You can also contact us directly, and we will provide you with a solution for distribution network automation.
It should be noted that the switching frequency cannot be too high to avoid damage caused by frequent action of the capacitor. At the same time, it is necessary to reasonably choose switching according to the actual situation of the power grid

Why Do Substations Use Stones, Gravel, Pebbles, and Crushed Rock?Why Do Substations Use Stones, Gravel, Pebbles, and Crushed Rock?In substations, equipment such as power and distribution transformers, transmission lines, voltage transformers, current transformers, and disconnect switches all require grounding. Beyond grounding, we will now explore in depth why gravel and crushed stone are commonly used in substations. Though they appear ordinary, these stones play a critical safety and functional role.In substation grounding design—especially when multiple gr01/29/2026 -
Why Must a Transformer Core Be Grounded at Only One Point? Isn't Multi-Point Grounding More Reliable?Why Does the Transformer Core Need to Be Grounded?During operation, the transformer core, along with the metal structures, parts, and components that fix the core and windings, are all situated in a strong electric field. Under the influence of this electric field, they acquire a relatively high potential with respect to ground. If the core is not grounded, a potential difference will exist between the core and the grounded clamping structures and tank, which may lead to intermittent discharge.I01/29/2026 -
