Motor and generator testing

Electric motor test and monitoring solutions

Looking for Baker Instrument Company? We are now part of Megger!

Baker Instruments’ electric motor analysers fall into three categories:

• Static analysers are used on off-line motors and generators to test motor circuit and insulation condition.
• Dynamic analysers are used for monitoring on-line motors to capture power quality, motor condition and load issues.
• Electric motor QC systems are designed for motor, generator and coil manufacturers to test the insulation and other parameters of coils, stators and armatures rapidly and repeatably in a production context.

Baker AWA-IV
STATIC MOTOR ANALYSER

• Range includes 2 kV, 4 kV, 6 kV and 12 kV models
• Testing capabilities include: surge, winding resistance, Megohm, PI, DA, continuous ramp DC step-voltage, and DC hipot tests
• 12 kV HO (high-output) version for performing surge tests on large motors and generators
• Compatible with Baker PPX Power Packs to extend insulation testing voltage range (6 kV, 12 kV and 12 kV HO versions only)
• IEEE- and IEC-compliant surge test
• Surge waveform comparison by the patented Pulse to Pulse Error Area Ratio (PP-EAR) technique
• Incorporates advanced inter-turn assessment capabilities in a field portable instrument
• Microsoft Windows 7 Embedded operating system
• USB port for data transfer and printing with Windows 7 plug-and-play printers

Baker DX
STATIC MOTOR ANALYSER

• Comprehensive range of tests in one instrument
• Configurable to meet needs and price point
• 4 kV to 12 kV for wide spectrum of motors and coils
• Compatible with the Baker PPX Power Packs for testing up to 40 kV

Baker PPX Power Packs
STATIC MOTOR ANALYSER BOOSTER

• Used to extend insulation testing range of AWA-IV static motor analysers and DX analysers
• Test voltages from 5 kV to 40 kV
• Available in three models (PPX30, PPX40, PPX30A)
• Mobile, large-wheeled cabinet for easy transport to the test area
• AC outlet on cabinet for the host unit (i.e., AWA-IV or DX), as well as lead storage
• Baker PPX30A includes an internal armature test circuit built in for testing large DC motors. When in armature mode, test voltage is limited to 2100 V and the current available is increased up to 7000 A.
• Complete range of tests (surge, winding resistance, Megohm (PI, DA), continuous ramp DC step-voltage, and DC hipot tests).

Baker EXP4000
DYNAMIC MOTOR ANALYSER

• 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

Baker NetEP
ONLINE MOTOR ANALYSIS SYSTEM

• Monitors motor systems for any degradation of performance, poor power quality and adverse load conditions
• Built upon the proven motor system monitoring technologies of the Baker EXP4000 Dynamic Motor Analyser
• Features proprietary data collection mechanisms that are coupled with standardized computer server and network technologies
• Operates with a single voltage measurement connection per voltage bus (up to 7 different voltage busses per single NetEP unit), and current sensors installed for each motor being monitored
• Continuously monitors and analyses more than 120 electrical parameters on up to 32 motors, compares results to user-defined thresholds and generates alerts if these threshold limits are crossed
• Two data acquisition methods are provided: power quality (acquired every ten seconds) and time waveforms (acquired once per hour)
• Tracks motor on/off cycles, determines load mismatches and identifies any adverse load oscillations or overloads
• Generates alerts for environmental factors such as excessive heat on a given motor’s operation
• Enables an organization’s critical motor assets to communicate if and when they are malfunctioning or experiencing a problem that could lead to failures or downtime
• Microsoft Windows 7 operating system

Baker WinAST
AUTOMATED STATOR TESTING SYSTEM

• Fully automated, full-spectrum quality control testers for motor manufacturers
• Built to each customer’s specifications using proven, reliable standard components in a cabinet style rack design
• Standard tests include: AC and DC hipot (with micro-arc detection to detect any breakdowns to ground – the only proven method to accurately detect any such faults), surge, inductance, corona and temperature-compensated resistance test capabilities
• Rotation-direction test (optional) for testing stators and field coils
• Configurable with a range of additional test capabilities
• Highly-sensitive computer-controlled testing, analysis and report generation software making testing virtually automatic
• Features a Microsoft Windows 7- based application with an intuitive, menu driven user interface
• Tests manufacturing processes as well as manufactured products
• May be integrated into fully automated lines with automatic fixtures and a PLC (or host computer) communications interface
• Designed for many years of rugged industrial use
• Recalibration may be done on-site with adjustments to software coefficients via a simple menu (and using ISO procedures)
• A high-voltage version of the Baker WinAST – the HV WinAST – is available for conducting tests on low inductance form coils and motor stators of more than 500 kW, or more than 575 V AC.

Baker WinTATS
TRACTION ARMATURE TESTING SYSTEM

• Traction armature quality control test system for motor manufacturing applications
• AC and DC hipot (with micro-arc detection to detect any breakdowns to ground – the only proven method to accurately detect any such faults), surge, bar-to-bar, and temperature-compensated resistance test capabilities
• User-programmable pass/fail limits
• Under 18 minutes to test as many as 200 armature bars (once the system is programmed and set up)
• Easy detection of weld faults (i.e., poor connection between coils and commutator) – the most frequent fault encountered in the manufacturer of armatures – with resistance testing
• System has a rack style cabinet, a computer running Microsoft Windows 7, power supplies and measurement circuitry, and includes an automatic armature indexing stand
• Semi-customized instrument assembled from standard components to the customer’s specifications
