HISAC Ultima with DCRM+ Circuit Breaker Analyser

The HISAC Ultima with DCRM+ is a state-of-the-art circuit breaker analyser and dynamic resistance measurement system designed for comprehensive testing of medium- and high-voltage circuit breakers. It performs all standard timing and motion analyses while integrating Dynamic Contact Resistance Measurement (DCRM) to assess main and arcing contact condition during operation. Featuring high-speed data acquisition, precision sensors, and PC-based reporting, it sets a new benchmark for breaker diagnostics and predictive maintenance.

Key Features

  • Measures timing, motion, coil current, and contact resistance (DCRM) in one test

  • Performs O, C, O-C, C-O, and O-C-O sequences

  • Dynamic Resistance Measurement (DCRM+) captures milliohm-level resistance changes during operation

  • High sampling rate for detailed waveform acquisition

  • Supports linear and rotary travel transducers

  • 12-channel timing with 2 motion channels and 2 coil inputs

  • PC-based software for waveform analysis and report generation

  • Built-in database for test history management

  • Rugged portable design for field and laboratory testing
