Low Voltage Ride-through
Electrical Engineering · Energy Engineering · Last updated: July 30, 2026 · How this entry was written
Definition: Low voltage ride-through is the capability of an electrical device, typically an inverter or generator, to remain connected and operational during a temporary voltage dip or sag on the power grid. This requirement ensures grid stability and prevents unnecessary disconnection of renewable energy sources during faults.
Example in context
“The solar inverter must comply with the grid code requiring low voltage ride-through capability for voltage sags down to 15% of nominal for 500 milliseconds.”
“Güneş invertörü, nominal değerin %15'ine kadar düşen ve 500 milisaniye süren gerilim düşümlerinde düşük gerilim üstesinden gelme kapasitesi gerektiren şebeke koduna uymalıdır.”
Where engineers use it
This term appears in grid interconnection requirements for wind and solar power plants. Engineers use it to design inverters that remain online during short voltage dips, preventing widespread blackouts and ensuring compliance with national grid codes.
Synonyms: LVRT, fault ride-through (specific to low voltage)
Antonyms: voltage swell ride-through
In Energy Engineering
Low voltage ride through (LVRT) is the capability of a wind turbine to remain connected and continue operating during a short-duration voltage dip on the grid. It is a grid code requirement for stable system operation.
“Modern wind turbines are designed with low voltage ride through capability to prevent disconnection during grid faults.”
Practice: can you use “Low Voltage Ride-through” at work?
You are commissioning a 50 MW solar farm and need to verify that each inverter can ride through a three-phase fault that reduces voltage to 20% for 200 ms. How do you test and document compliance?
Show a model answer
“All grid-connected inverters must be tested for low voltage ride-through performance.”
