Overview of Synchronizing Panel

Intelligent Power Source Synchronization for Critical Applications

A Synchronizing Panel is an advanced electrical control system designed to synchronize, control, and manage multiple power sources such as DG sets, utility grid (mains), solar power systems, and other captive energy sources. It ensures that all connected sources operate together safely by matching voltage, frequency, phase sequence, and phase angle before connection to a common bus.

AAVAD Instrument Pvt. Ltd. engineers and manufactures high-performance Synchronizing Panels for installations where power continuity, load stability, and operational reliability are mission-critical.

Why Synchronizing Panels Are Essential

In modern industrial and infrastructure facilities, reliance on a single power source is no longer practical. Synchronizing Panels enable:

• Seamless power continuity during mains failure

• Efficient utilization of multiple DG sets

• Stable load sharing across power sources

• Integration of renewable energy with conventional power

• Reduced downtime and operational losses

These panels form the backbone of critical power systems in manufacturing plants, utilities, data centers, hospitals, and large commercial facilities.

Principle of Operation

All power sources are connected to a common busbar system through motorized circuit breakers or air circuit breakers (ACBs). The Synchronizing Panel continuously monitors electrical parameters.

Operating Sequence:

1. Panel monitors mains and alternate power sources

2. On mains failure, synchronizing relay initiates DG start command

3. DG sets warm up and stabilize

4. Synchronizing relay matches voltage, frequency, and phase

5. Load is shared automatically between sources

6. On mains restoration, load is transferred back smoothly

This process ensures zero interruption and safe power transition.
