Corona effect is an electrical phenomenon. It happens in high voltage transmission lines. This effect causes a buzzing noise and power loss. It also produces light around the conductors.
Why Does Corona Effect Happen?
Corona effect happens because of ionization of air around the wires. When voltage is high, it ionizes the air. This means it charges the air particles. These charged particles create the corona effect.

Factors Affecting Corona Effect
There are several factors that affect the corona effect. Here are the main ones:
- Voltage: Higher voltage means a stronger corona effect.
- Conductor Size: Larger conductors reduce the corona effect.
- Weather: Rain and fog increase the corona effect.
- Air Pressure: Lower air pressure increases the corona effect.
How To Reduce Corona Effect
Engineers try to reduce the corona effect. They use different methods. Here are some common ways:
- Increase Conductor Size: Bigger wires help reduce the effect.
- Use Bundled Conductors: Grouping wires together helps too.
- Improve Insulation: Better insulation reduces ionization.
Effects Of Corona On Transmission Lines
Corona effect has several impacts on transmission lines. Some are good, but most are bad. Let’s look at them:
Power Loss
Corona effect causes power loss. This is not good for the power system. It reduces the efficiency of power transmission.
Noise
Corona effect creates a buzzing noise. This can be annoying. It can also interfere with communication lines.
Light
Corona effect produces a faint light. This light can be seen at night. It is usually blue or purple.
Ozone Production
Corona effect produces ozone. Ozone is a type of oxygen. It is not good for health if inhaled.

Good Effects Of Corona
Corona effect is mostly bad. But it has some good effects too. Here are a couple of them:
Reduce Sudden Increases In Voltage
Corona effect can help control sudden increases in voltage. This can protect the power system from damage.
Self-cleaning Effect
Corona effect can help clean the conductors. It removes dust and other particles from the wires. This helps maintain the transmission line.
Frequently Asked Questions
