The Megger's Baker EXP4000 is a powerful tool, designed for site use, to analyse the motor running under its normal load. It tracks multiple data types to identify trends that indicate potential problems. Voltage and current are measured and a series of parameters are then calculated, including power quality, rotor bar condition, % load, % operating efficiency, average torque value, torque ripple showing variation within process, monitoring of start-up transients (volts, current and torque) and much more.

- Monitors and assesses conditions across a running “machine system” that impact the health and performance of the motor within the system
- Evaluates the quality of incoming power fed to motor
- Assesses motor performance indicators
- Tracks the amount and condition of load placed on the motor
- Instrument connection options: at a motor junction box, at the instrumentation cabinet, inside a motor control cabinet (MCC), from outside an MCC (requires a Baker EP1000 (dynamic motor link))
- Designed for rugged site use in tight spaces typical of industrial environments
- AC or battery operation
- Visual confirmation of motor integrity
- Facilitates survey of plant-wide motor efficiency
- Microsoft Windows 7 operating system
