Electronic Voltage Burden
Electronic Voltage Burden M411
is a modern programmable device used as a load in the secondary circuits of Voltage Transformers during their verification and calibration
With the wide programmable burden power range provided, most national and international standard burdens or specific customer values can be set
FEATURES AND BENEFITS
- Wide range of burden power values for VT in accordance with standards: IEC 61869-3, IEC 61869-5, IEC 60044-2, IEC 60044-5, IEEE C57.13, GOST 23625, GOST 1983
- Standard and non-standard values of burden power with standard and non-standard rated secondary voltages
- Extended range of rated voltage factor FV up to 250 %
- 100 % and 25 % rated burden power, cosφ = 0,8 at rated frequency 50 and 60 Нz
- 100 % and 0 % rated burden power, cosφ = 1 at rated frequency 50 and 60 Нz
- Compensation resistance of the cable used for connect to the secondary winding
- Connection to two branches of a multiple-tapped winding
- Simple use by intuitive user interface
- The ability for the user to create his own range of frequently used burden values
- Possibility of using with automated VT calibration systems
- Small size and low weight
