Circuit Breaker Analyzer allows the off-line testing of MV and HV circuit breakers. The test set measures circuit breaker operation times as they are defined in the IEC standard 62271-100

MI 3252 MicroOhm 100A is a portable low resistance ohmmeter used to measure low contact resistances of breakers and switches, busbars using test current from 100 mA to 100A. 

MEASURING FUNCTIONS

• Bidirectional resistance measurement from 0,1 µΩ up to 2000 Ω with test current up to 10 A
• Temperature compensation (with optional temperature probe)

KEY FEATURES

• Highly efficient 10 A current source generates 10 A into 200 mΩ load for 15 min without overheating.
• High overvoltage protection (CAT IV / 300 V) allows measurement in substations and other points with low line resistance.
• Internal protection cicuit protects user and instrument from inadvertent connection to lines.
• Custom limits can be set for PASS / FAIL evaluation of test result.
• 50 Hz / 60 Hz ripple detection and rejection.
• Instrument can be powered from mains or internal rechargeable battery. Instrument can be normally used while built-in fast battery charger charges the NiMh batteries.
• Large 320 x 240 dots matrix LCD offers easy-to-read results and all associated parameters.
• Lightweight portable design.
• Up to 1000 test results with timestamp can be stored in internal memory.
• PC SW HVLink PRO enables downloading, review, analyses and printing of test results.
