Electronic Current Burden (1A)
Electronic Current Burden M400 is designed to provide a programmable burden in the secondary circuits of current transformers during verification, calibration, and testing. The device is intended for use with current transformers having a nominal secondary current of 1 A
FEATURES AND BENEFITS
- Wide range of burden values according to standards: IEC 61869-2, IEC 60044-1, IEEE C57.13
- Rated current – 1 A
- Rated power range: 0,5 to 50 VA, cos φ = 0,8 at 50 Hz 0; 0,5 to 50 VA, cos φ = 1 at 50 Hz
- Input cable, contact and internal test set resistances are compensated by four-conductor connection
- Non-breaking measuring circuit during switching of the burden
- Possibility of using with automated current transformer calibration systems
- Small size and low weight
VERSIONS
Electronic Current Burden М400 is available in two versions:
- М400.1 allows current transformer calibration in secondary current range 1…120 % of rated current
- М400.2 allows current transformer calibration in secondary current range 1…150 % of rated current
APPLICATIONS
Electronic Current Burden M400 is used by:
- Manufacturers of Current Transformers
- On-site testing of Current Transformers
- Calibration laboratories
- Metrology institutes
