Advanced Testing Capabilities
Precise measurement of transformation ratios and accuracy class verification. Ensures metering accuracy from 0.1% to 3% class specifications with automated calculation of ratio errors.
Instantaneous polarity testing to ensure correct phase relationships. Critical for proper relay coordination and preventing reverse power flow indications in protection systems.
Measures actual connected load on transformer secondary. Verifies that the burden doesn't exceed rated values, ensuring accuracy is maintained under real operating conditions.
High-voltage insulation testing (typically 1000-5000V DC) to verify dielectric integrity. Detects moisture ingress, contamination, and aging that could lead to failures.
Excitation characteristic measurement for CTs. Identifies knee-point voltage to ensure proper operation during fault conditions and prevent relay mal-operation.
Measures phase displacement between primary and secondary. Critical for power metering accuracy and revenue calculations, especially in precision 0.1 and 0.2 class applications.
