Overview

This instrument accomplished fully remote monitoring from the Motor Control Center (MCC), is a non-hazardous low-voltage battery operated unit, and is highly portable and durable for use in even the tightest and most rugged circumstances.

• This in-service motor analyzer takes the next step in providing complete P/PM programs. It provides root cause analysis through the separation of mechanical and electrical issues. The EXP3000R was superiorly designed to pinpoint challenges (voltage source, VFD, motor, load) your rotating machinery faces. This self-contained portable instrument is computer driven with proven engineering, allowing all testing to be accomplished directly from the MCC or from the Baker EP connection.
• The EXP3000R performs seven major functions in a complete predictive maintenance program. It identifies possible power circuit problems that degrade motor health, examines overall motor power conditions, monitors the load and observes motor performance plus estimating energy savings. It is programmed to supply information on voltage level, voltage balance, harmonic and total distortion, rotor cage condition, motor efficiency, effective service factor, overcurrent, operating condition, torque and load.
• Once testing is completed, results can be saved and stored for each individual motor. This type of documentation is critical for any predictive maintenance program. It allows the recalling of previous information for true trending capabilities. With the EXP3000R, test results are collected, stored, recalled and managed using standard MS Access® relational database file formats. Reports can be generated quickly and easily through the main print console, allowing operators visual confirmation of motor integrity.
• Survey plant wide motor efficiency with the EXP3000R and determine load mismatches, oscillating load, and transient peak energy. It 's on-line capabilities allow accurate assessment of operating load conditions over time. Results are immediate and show operating efficiencies allowing you to determine the true cost of wasted energy.
• Test Domains

  • Power Quality: Identifies non-optimal power quality problems which cause additional undue stress to the motor. The voltage level, voltage balance, harmonic distortion, total distortion, power and harmonics test flag frequent problems. This can consist of wrong settings on supply transformer's taps, poorly distributed single phase loads, overloading (saturating) supply transformers, excessive VFDs on low voltage busses, excessive non-harmonic frequencies on a VFD, missing line-inductors on VFD applications and missing or open power factor correction capacitors.
  • Machine Performance: This group of tests conclusively evaluates the present operation of the motor, identifying stressful operation and its source. It looks at Effective Service Factor, Load, Operation Condition, Efficiency, and calculates Payback Period. Common problems found in this area include: Thermal overloading of the motor, recognizing the deterioration of the machine among other items that are directly related to the motors health and the energy waster in its inefficiencies.
  • Current: This set of tests identifies problems within the entire machine system. Those tests include: Overcurrent and Current Unbalance. These tests look at the health of the entire system and describe a problem within this system as it is related to current. This domain identifies problems, however the root cause may not be apparent.
  • Spectrum: This domain has the rotor bar test along with the V/I Spectrum, Demodulated Spectrum, and Harmonics. This domain shows the current an voltage relationships with regard to frequency. It will electrically find saturation problems, broken rotor bars, excessive VFD drives on low voltage busses and it can verify mechanical problems.
  • Torque: The torque domain is a highly important breakthrough for Baker Instrument Company. These tests, Torque Ripple and Torque Spectrum, enable the user to find a numerous amount of problems quickly and accurately. THis domain specializes in diagnosing mechanical issues, shows transient overloading, finds mechanical imbalances along with bearing problems, cavitation and many other items.
  • Connections: This portion of the EXP3000R offers multiple additional tools, including phasor diagrams, 3 currents, 3 voltages, and harmonic bar charts, instantaneous voltage, frequency, symmetrical components, and speed traces for dynamic VFD applications. Jointly these tools assess bearing health.
  • VFD Monitoring (Optional): Baker Instrument designed the EXP3000R as a comprehensive monitoring tool. Along with any three phase induction motor and generator, it will also monitor the activities of Variable Frequency Drives (VFD) applications and AC servo motors. For the first time diagnosis of motor problems can occur even under the most demanding VFD operation. This optional VFD3000 software shows how frequency, speed, torque, and voltage level vary with respect to time.
  • Continuous Monitoring: The newest feature of the EXP3000R is the CM3000 or Continuous Monitoring software. This software enables the user to monitor upwards of 41 data points real time. This real time and continuous data gathering cp ability will give immediate impact in finding intermittent problems with motors such as electrical tripping. This user customizable software enables the operator to collect real time data on whatever is deemed the most important to the operation. This portion of the EXP3000R will also act as a power Analyzer to determine actual power quality. This tool is another innovation from Baker Instrument that enables the user to further develop comprehensive predictive maintenance programs.
  • Transient Analysis: The EXP3000 can perform a startup transient analysis with a integrated tool. The traces are 2 cycle windowed rms currents and voltages of all three phases. This data can be zoomed, panned, and the available cursors allow readings of levels and time in the graphs.
