Making Outages a thing of the past

What if your power line could autonomously distinguish between a transient fault and a permanent fault, seamlessly restoring power without human intervention—wouldn't that redefine grid reliability?

In the realm of power distribution, where milliseconds can determine outages, NIKUM's AVR (Advanced Vaccum Recloser) emerges as a game-changer. It’s not just a device; it’s the brain of your distribution line. The AVR autonomously identifies faults, isolates them, and decides whether to restore power or keep the circuit open, ensuring unparalleled grid reliability and safety.

Let’s break it down using the diagram above, which illustrates the precise timing and operational sequence of a recloser like the AVR.

How the AVR Operates: Simplified and Step-by-Step

1. Fault Detection: The AVR continuously monitors the power line. When it detects an abnormal condition (like a fault caused by a tree branch or lightning), it triggers its protection mechanism.
2. Opening the Circuit: The AVR sends a signal to open the circuit breaker, stopping the flow of electricity. This ensures the faulty section is isolated from the rest of the grid.
3. Dead Time: After opening, the AVR waits for a brief pause (called Dead Time) to see if the fault clears itself (like a branch falling off the line or lightning passing).
4. Fault Analysis: During this pause, the AVR determines the type of fault:
5. Reclosing the Circuit: If the fault is transient, the AVR sends a signal to reclose the circuit breaker. This reconnects the power, and electricity flows again.
6. No Reclosing for Permanent Faults: If the AVR identifies a permanent fault, it keeps the breaker open to prevent further damage or safety risks.

Why It’s Smart:

• Self-Healing Grid: The AVR restores power automatically after temporary faults.
• Safety First: For permanent faults, it prevents further damage by keeping the circuit open.
• Precise Timing: Every step—opening, waiting, and reclosing—happens in milliseconds, ensuring quick and efficient operation.
• It’s fully compatible with advanced systems like SCADA, 5G, 4G, and IoT, enabling seamless integration, real-time monitoring, and enhanced connectivity.
