Harmonic Filters

Designing filtering solution to mitigate harmonics problem in power supply system is not easy. System resonance may be resulted if harmonic filters are not properly chosen or sized. There are a number of ways to achieve harmonic mitigation and it really depends on practical experience to finalize a feasible solution. PTAL has experts who have more than 10 years of experience in harmonics measurement, handling and mitigation. This enables PTAL to be accurate and to the point in proposing harmonics mitigation solutions. We can propose one of the following solutions: 

• passive harmonic filters 
• active harmonic filters 
• isolation transformers 
• K-rated transformers 
• Power factor correction capacitors
