KRD Smart Capacitors Overview
KRD Smart Power Capacitor is a unique product for power factor correction. It is new generation of reactive power compensators, which can make low-voltage distribution network energy-efficient with minimum line losses and ultimately improves its quality and power factor. Each of this capacitor is a small PFI plant by itself without any assistance from additional component. It has all necessary components for power correction built-in, like circuit breaker for capacitor protection, Programmed MCU, switching module, relay for controlling, LED display for important parameters and settings display, and harmonic reactor for harmonics filtration. KRD capacitor makes sure switching at zero-point which nullifies inrush current. It can also communicate through RS-485 with central distribution control. This makes KRD an advance capacitor which is compact, intelligent, innovative and modular.

working Principle
KRD Smart Power capacitors are composed of power capacitor, harmonic reactor, intelligent control unit, synchronous switching module, and an LED display and measurement and protection unit. Power parameters measured by different sensors and temperature measured by temperature sensor are sent to intelligent control unit through a dedicated terminal. Intelligent control unit of KRD smart capacitors acts as an intelligent relay and controls capacitors. It collects signals coming from different sensors, processes it, calculates the accurate capacity and starts to detect zero crossing of grid voltage. When zero crossing arrives, it closes magnetic latch relay (part of Intelligent control unit) and capacitor starts operation. This zero point switching guarantees zero inrush current, long service life and elimination of multiple components in traditional PFI panel.
When multiple capacitors are connected in series, it is recommended to use controller (KRD600) for controlling the whole system. One capacitor is connected with this controller and other capacitor communicate with each other through that connected capacitor. In case of failure of controller, each capacitor will be switched to manual mode one by one. All settings will be carried out through LCD. Thus, all capacitors will be operating without any controller.

FAQ
1. Does this KRD capacitor operates through separate relay?
Each KRD capacitor has its own intelligent controlling unit which acts as relay. When many KRD capacitors are connected together in smart PFI cabinets, the whole system can operate without any separate relay as one built-in controller of capacitors will act as relay. But it is recommended to use KRD600 controller which is special controller for smart capacitors and can operate 32 capacitors together.
2. Why we need KRD600 controller when we already have built-in controller?
KRD600 controller is a recommended component to act as main control PFI Panel. Built-in controller are recommended when main controller is malfunctioning. In such cases, all capacitors are turned to manual mode, settings (like PF) are made on built-in LCD display and whole cabinet starts operation through built-in controllers.

3. How do you compare KRD capacitor with traditional in terms of price?
Much better comparison is between smart PFI cabinet with traditional PFI cabinet as both are complete PFI system. When we compare KRD smart capacitor with traditional capacitor, KRD capacitor is expensive as it is complete PFI unit and has built-in controller, relays, LCD display, breaker, etc. While traditional capacitor is just a capacitor and needs multiple components to turn into complete PFI unit.
4. How about residual current during unwanted power interruption?
KRD Smart Capacitor has built-in discharge resistor which discharges residual current in case of any non-zero point switching.
5. How do we setup manual or automatic operation in smart PFI cabinet?
You can select auto/manual mode through KRD600 controller as well as through capacitor LCD.
6. How KRD Smart Capacitor deals with inrush current?
KRD smart capacitor ensures zero inrush current through zero-point switching. Switching module of KRD capacitors is programmed in such a way that it can only switches at zero-point of AC curve. Thus leaving no chance of inrush generation.
