Megger BAKER AWA-IV/12 Static Motor Analyzer

Overview

The Megger BAKER AWA-IV/12 is an automated high-voltage insulation testing instrument for diagnosing the condition of motor and generator insulation systems and motor circuit imbalances. The system performs user-programmable test sequences that can be configured in the office and deployed consistently across field testing routes. The embedded computer executes tests with microsecond precision, monitors voltage levels continuously, and interrupts testing immediately if insulation weakness is detected.

Key Features

• Automated test sequences programmed and deployed before field use
• Winding resistance and insulation resistance measurements
• Dielectric Analysis (DA) and Polarization Index (PI) testing
• DC Step-Voltage, DC Continuous Ramped, DC Hipot, and Surge tests
• Patented Pulse-to-Pulse Error Area Ratio (PP-EAR) technique for turn-to-turn fault detection
• Detects shorts among parallel windings with sub-one-percent coil sensitivity
• Microsoft Access database format for test result management and archival
• Centralized data analysis for multi-tester and multi-route asset monitoring
• Automatic voltage ramp with early termination on insulation weakness detection

Applications

• Predictive maintenance testing for motors and generators in operation
• Factory acceptance testing of new rotating equipment
• Service depot failure diagnosis and root-cause analysis
• Turn-to-turn winding defect detection and inter-winding fault location
• Trending and condition monitoring across maintenance routes

Included Accessories

• Power cord and test leads
