Voltage Transformer Test Set
Voltage Transformer Test Set M210/M211 uses a high-voltage capacitance bridge method to deliver unmatched accuracy in measuring voltage transformer errors across continuous primary and secondary voltage ranges. By replacing bulky traditional designs, this technology provides reduced equipment size and weight for effortless field operation.
Voltage Transformer Test Set M210/M211 can also serve as a high-voltage capacitance bridge to measure capacitance and dissipation factor (tan δ) during high-voltage equipment testing*
* Additional function. Can be supplied upon customer’s request
FEATURES AND BENEFITS
