Harmonic Filter Solution for European Grid

Case Study: Harmonic Current Mitigation for European Grid Compliance

Nuotian Technology delivered a tailored harmonic filtering solution to help a client meet stringent gridstandards in European markets,

reducing harmonic current injection into public power networks and ensuringfull regulatory compliance.

Challenge
The dlient's equipment was injecting excessive harmonic currents into the public grid, which failed to meet thestrict harmonic requirements

of European countries and other regions with high grid quality standards. Thisposed a risk of non-compliance and potential operational disruptions.

Solution
We provided a customized harmonic filtering system, offering clients the choice between:
Passive filters: Cost-effective, reliable, and ideal for stable harmonic loads.
Active filters: Dynamic, high-performance, and suitable for variable or complex harmonic profiles.
The selected filter unit was fully CE-certified, ensuring it met all relevant European safety and performancedirectives for grid-connected equipment.

Outcome
The harmonic current injection into the public power grid was effectively reduced to within permissible limits.
The client achieved full compliance with European grid standards, eliminating regulatory risks.
The CE-certified filter ensured seamless integration and reliable operation in European markets.
