HybridSolution
Harmonic Filters
ElhandHF™ Harmonic Filters allow to use the maximum system power, protect equipment from malfunction and extend the system lifespan.
- Power range: 2,2-2600 kW
- Frequency: 50 or 60 Hz
- Voltage range: 380–690 V
- Protection degree: IP00–IP66
- Cooling: air natural
- no fans to maximize the filter’s lifespan
Sine-Wave Filters
SWF Filters convert rectangular PWM voltage into sinusoidal one, thus eliminate harmful impact of the inverter transistors switching.
- Power range: 2,2-2600 kW
- Frequency: 0-200 Hz
- Voltage range: 380–690 V
- Protection degree: IP00–IP66
- Cooling: air natural
- no fans to maximize the filter’s lifespan
Step-Down Transformer Harmonic Filter Hybrid Solution
The Advanced Passive Filtering with a 6 or 12-pulse oil-immersed and hermetically sealed transformer designed into a single Hybrid unit, creates a new technology and solution for the ESP fields challenge. The Hybrid offers greater power efficiency in a smaller footprint (of at least 10%- 20% smaller than a conventional Step-Down Transformer plus Harmonic Filter), producing less harmonics and meeting the IEEE-519 – 5% THDI level. Improving the ESP power quality results in a longer transformer life as well as the entire oilfield operation – the ultimate goal for offshore/onshore applications.
