Electronic Voltage Burden
Electronic Voltage Burden M410 is used as a load in the secondary circuits of Voltage Transformers during their verification and calibration
FEATURES AND BENEFITS
- M410 sets burden power values for VT with rated secondary voltages 100/3, 100/√3, 100, 110/3, 110/√3, 110 V
- Rated power range:
1 to 10 V·A, cosφ = 1 at 50 Hz
5 to 600 V·A, cosφ = 0,8 at 50 Hz - Sets 100 % and 25 % rated power
- M410 can be integrated in a computer controlled test system in conjunction with Voltage Transformer Test Set M210/M211
- Voltage overload protection
- Wide range of emulated burden ratios
- Small size and low weight
APPLICATIONS
M410 is used by:
- Manufacturers of Current Transformers
- On-site testing of Current Transformers
- Calibration Laboratories
- Metrology Institutes
