Product Description

JYL-200A Loop Resistance TesterPower systems commonly use QJ44 double-arm DC bridges for transformer winding and HV circuit breaker contact resistance measurement.However, their test current is only mA-level, unable to detect conductor cross-section defects. Oil film and oxidation affect HV switch testing. Per SD301-88 regulations, 100A is required.
