A consistent and steady power supply is required for modern businesses to run smoothly. Such a little power failure in an industrial facility, hospital, data center or commercial building can result in lost productivity, safety risks, and monetary damage. A Diesel Generator Load Sharing Panel becomes crucial in this situation. By dividing the electrical demand equally, a DG demand Sharing Panel facilitates the effective operation of several diesel generators (DG sets). Industries employ many DG sets connected by a DG Load Sharing Panel rather than depending on a single generator to guarantee a steady power supply, increased efficiency, and lower fuel usage. Power system experts claim that load sharing improves dependability and avoids overload situations by ensuring a balanced distribution of electrical power between parallel generators.
What is DG Load Sharing Panel?
An electrical control panel used to distribute power load between two or more generators running simultaneously. The main purpose of a DG Load Sharing Panel is to ensure that each generator shares equal load and operates efficiently.
When power demand increases beyond the capacity of one generator, another DG set automatically starts and shares the load.
The system synchronizes important electrical parameters such as:
- Voltage
- Frequency
- Phase sequence
- Phase angle
These parameters must match before connecting generators in parallel operation.
Why is the DG Panel Important?
Industries rely on backup power systems to avoid operational interruptions. However, running multiple generators without a DG Load Sharing Panel can create serious problems.
Problems without DG Load Sharing Panel
- Generator overloading
- Unequal power distribution
- Voltage fluctuation
- Increased fuel consumption
- Reduced generator lifespan
- Unexpected shutdown
Load sharing ensures generators operate within safe limits while maintaining consistent power supply.
Working Principle of DG Load Panel
The DG Load Sharing Panel working principle is based on synchronization and equal load distribution between generators.
The panel continuously monitors electrical parameters and automatically adjusts generator output to maintain balance.
Step-by-Step Working of DG Panel
1. Generator Start
When power demand increases, the DG Load Sharing Panel automatically starts additional generators.
2. Parameter Matching
The panel checks voltage, frequency, and phase angle of each DG set before connecting them.
3. Synchronization
Once parameters match, generators are synchronized to operate together smoothly.
4. Load Distribution
The DG Load Sharing Panel distributes electrical load equally between generators.
5. Automatic Control
When power demand decreases, extra generators stop automatically to save fuel.
Load sharing allows multiple generators to divide active and reactive power proportionally, improving efficiency and stability.
Key Electrical Parameters Controlled by DG Load Sharing Panel
For safe operation, the DG Load Sharing Panel monitors several electrical parameters:
- Voltage balance
- Frequency stability
- Phase angle matching
- Phase sequence alignment
- Power factor balance
Matching these parameters ensures smooth and stable parallel operation of generators.
Main Components of Load Sharing Panel
A modern DG Load Sharing Panel consists of multiple electrical and electronic components that ensure accurate load distribution.
Important Components
- PLC Controller
- Synchronizing Relay
- Circuit Breaker (ACB/MCCB)
- Current Transformer (CT)
- Potential Transformer (PT)

These components monitor system performance and protect generators from overload, short circuit, and voltage fluctuation.
Types of Load Sharing in DG Load Sharing Panel
A Diesel Generator Load Sharing Panel mainly uses two types of load sharing methods:
Active Load Sharing
Active load sharing controls real power (kW) distribution between generators by adjusting engine speed.
Reactive Load Sharing
Reactive load sharing maintains voltage stability (kVAR) and ensures proper power factor balance.
Both active and reactive load sharing are necessary for efficient generator performance.
