Electronic Voltage Burden
Electronic Voltage Burden M411 is an advanced, programmable load simulator designed for the secondary circuits of voltage transformers during testing, verification, and calibration. Featuring a broad programmable power range, it effortlessly accommodates standard burdens defined by national and international regulations, as well as custom user-defined values
FEATURES AND BENEFITS
- 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 - A wide load range of up to 1200 VA allows the M411 to be used as a single device (monoblock) without additional power range extenders
- 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 2,5
- 100 % and 25 % rated burden power, cos φ = 0,8 at rated frequency 50 and 60 Нz
- 100 % and 0 % rated burden power, cos φ = 1 at rated frequency 50 and 60 Нz
- Resistance compensation of the cable used for connect to the secondary winding
- Connection to two taps of a multiple-tapped winding
- The ability for the user to create his own range of frequently used burden values makes operation simple
- Possibility of using with automated VT calibration systems
- Ensuring safe operation with continuous voltage monitoring
- Protection against user setting errors, overvotage and overheating
- Simple use by intuitive user interface
- Integrative 5,7’’ touch screen
COMPLETE TEST SYSTEM
Integrating the M411 into a computer-controlled test system is enabled by combining it with:
- M100 Comparator
- M120 Voltage Transformer Test Set
- S250 High-Voltage Source
APPLICATIONS
Electronic Voltage Burden M411 is used by:
- Manufacturers of Voltage Transformers
- On-site testing of Voltage Transformers
