CWP/CWL Series
Current Transformers
High Precision 50 Hz KWh-meter Current Transformer
Features
- Negligible amplitude error due to low core losses.
- Reduced phase error due to simple electronic
calibration.
- Improved stability of the permeability across the entire
temperature range.
- Reduced core size or number of windings.
- Frequency 50/60 Hz.
