Harmonics: The hidden challenge in renewable energy projects
The challenge: harmonics and partial discharge
In underground high and medium voltage (MV) networks, cable joints and end closures are often the weak links. For solar and wind farms, where reliability is crucial, these points increase the risk of failures. Harmonics are caused by non-linear loads (inverters) and can result in accelerated aging or unexpected failure of cable accessories.
What are the effects of harmonics on cable joints?
- Increased risk of partial discharge (PD) in the insulation materials.
- Heat generation/hotspots in the cable accessories – for example in field control.
- Thermal aging of materials – for example in the shrink and insulation material.
The solution: LoviSil® liquid silicone technology
LoviSil® is an innovative liquid silicone technology that eliminates these risks and significantly extends the life of cable connections in sustainable projects. The advantages of LoviSil®:
- No partial discharge: The liquid silicone is insensitive to partial discharge (PDs) due to its restorative properties.
- Geometric field control: Field control that is insensitive to harmonics so that no hotspots occur.
- Thermal stability: The Protolin® seal is resistant to extreme temperature changes and insensitive to thermal aging.
