Simplifying Phase Identification in Power Networks with Synchrophasor Technology
In power systems, it’s important to know which phase you’re working on. This is called phase identification.
It helps when installing new meters, balancing loads, or keeping the power grid working properly.
Getting the phase right means fewer mistakes, less wasted energy, and better data for managing the network.
🔎 Why Phase Identification Matters
EleElectricity networks have three phases: A, B, and C. It is important to know the path of each phase. Here are a few key reasons why:
- To install and fix equipment safely
- To stop faults between phases
- To balance loads and reduce neutral currents
- To help power companies build accurate network models
But figuring out the right phase in the field can be tricky.
Sometimes, the network maps are old or wrong.
The usual methods take a lot of time, effort, and can lead to mistakes—especially when transformers change the phase angles.
⚡ How Synchrophasors Improve Phase Identification
Dewesoft’s innovative approach uses synchrophasor technology — GPS-synchronized measurements that allow comparison of phase angles at different locations within the .
Synchrophasor technology uses GPS timing to measure and compare phase angles in the power network. This helps determine which phase is which, even in different locations.
Here’s how it works:
- You set up a reference device at a known location, like a substation.
- A field technician connects a handheld tool to any part of the low-voltage network.
- Both tools measure the phase angle of the voltage at the same time. People use GPS to ensure the timing is exact.
- The system compares the two readings and tells you if it’s phase A, B, or C — even if the two spots are far apart.
This method removes guesswork. It also avoids slow, manual testing and makes phase identification much faster and more accurate.
✅ The Bonus: Automatic Phase Shift Compensation
One of the biggest challenges in phase identification is dealing with phase shifts caused by transformers. Firstly, these shifts distort phase angles and confuse traditional measurement methods.
Dewesoft’s system solves this with a patented compensation algorithm. It:
- Automatically recognises transformer vector groups
- Adjusts calculations to account for phase shifts
- Provides correct phase identification despite the transformer’s impact
The result? Reliable phase identification without needing detailed transformer data or manual adjustments.
🔧 Applications Across the Power Sector
This technology is a game-changer for:
- Utilities and DNSPs managing vast low-voltage networks
- Smart meter installers needing accurate phase mapping
- Renewable energy projects connecting solar or batteries to the grid
- Power quality engineers addressing load imbalance and neutral current issues
