K-factor transformer also named as K-factor rating transformer, could be applied in the non-linear load electrical circuit, K-factor is a weighting of the harmonic load currents in the light of their effects on the heating of the transformer.
- Full K rating series(K1,K4,K9,K13,K20) transformers are available in Shinenergy
- Specially applied in the non-linear load circuit
- Prevent power system problems the harmonics currents
- CE, UL certificated
Outstand Capability of Handling the Harmonic
The main feature of the K-factor transformer is handling the harmonics, with the better capability of handling harmonics compared with the typical transformers, the different K rating number is the indication of the amount of harmonic current that the transformer could handle, output of the K-factor transformer are non-linear load.
Better Temperature Resistance
Shinenergy’s K-factor transformer with better temperature resistance compared with the typical transformers, K-factor transformer won’t overheat when the temperature rises in a short time.
Q1: What’s the advantage of the K-factor transformer?
A1: The K-factor transformer is specified for handling a degree of harmonic load currents without overheating.
Q2: What’s the meaning of the K-factor?
A2: K-factor is the ratio between the extra losses caused by harmonics and the eddy current losses at 60Hz, the K-rating number indicates the amount of harmonic current that the transformer could handle.
Q3: What’s the difference between different K-factors?
A3: K-rating factors 4,9,13, 20 are available, typically as the K-factor of the transformer increases, the transformer size and cost increase, low load efficiency (<25% load) decreases, and impedance decreases.
Working Principle of the K-factor Transformer
Shinenergy could provide the UL-certified full series K rating transformers. The K-factor is the value that indicates how effectively a transformer could handle the harmonic current, as well as keep the temperature rise within a limits, the main differences between K-factor transformers and typical ones are better temperature rise control and better handling of the harmonic currents.
