Product description
UNI-T UT513A is a professional insulation tester designed for inspection and analysis of insulation resistance in electrical installations, industrial systems, and electrical equipment. The instrument supports test voltages up to 5000V and can measure insulation resistance up to 1000GΩ. The UT513A includes PI and DAR measurement functions together with data storage and USB communication for documentation and analysis. PI and DAR measurements are used to analyze insulation quality over time and can help detect moisture, insulation aging, and contamination before failures occur. The UT513A is primarily used for insulation testing of transformers, power cables, motors, generators, and other equipment where high test voltages and detailed insulation analysis are desired.
