STATIC MOTOR ANALYSER Baker AWA-IV

Description

Static motor analyser DX Series provides the industry’s most comprehensive set of tests to analyze a motor’s entire insulation system. Portable, powerful, and configurable to meet the specific needs of motor shops, industrial maintenance teams and motor OEMs and others.Baker DX series analyzers detect every common electrical problem with industrial motors. In both random and form wound coils and windings, a Baker DX can identify incorrect numbers of turns, wire gauges or wire material. It also detects open, reversed or unbalanced coils.DX Series analyzers find early indications of insulation weakness and faults in windings, between phases, coil-to-coil and in groundwall insulation. They can identify if contamination by chemicals, moisture, dust or dirt is impacting insulation strength. Additionally, they detect problems with motor connections such as feed cable insulation weaknesses, imbalances, opens or high resistances.DX Series offers models :4 and 6KV,6KV HV,12KV,12KVHO,15V

The industry-leading, standards-compliant range of tests includes:

• Winding resistance
• Inductance
• Capacitance
• Impedance
• Phase angle and D/Q
• Insulation resistance
• Dielectric absorption (DA)
• Polarization index (PI)
• Step voltage
• DC hipot
• Surge
• Surge PD (partial discharge)
• Rotor influence check (RIC)

 Baker DX  features:

• 4 to 40kV max test voltages to perform tests on a full spectrum of motor and coils (fractional horsepower motors up to multi-megawatt generators)
• High- and low-voltage test capability in a single instrument to test motor circuit and insulation systems
• Intuitive graphical user interface with large, glove-friendly touch screen
• USB printer and flash drive interface for easy report printing and data transfer
• Coil mode enables rapid testing of coils and storage of all data

Partial discharge

High voltage equipment can suffer from partial electrostatic discharge, where localized corona or breakdown discharge can damage insulation, leading to progressive degradation and eventual circuit breakdown.Winding insulation defects of this type can be found early with the optional Baker DX Surge PD capability, which captures inception, repetitive inception, repetitive extinction and extinction voltages of partial discharge (PD) in accordance with the IEC 61934 standard. PD waveforms and data are included in reports generated by the Baker DX and the Surveyor DX desktop PC software application

DC Motor testing

DC motor testing is quick and accurate using the Baker DX. The tester includes an armature test mode user interface and reporting function. Interpole and field coil test results are specially labelled. Bar-to-bar and span tests can be performed on a DC armature to thoroughly analyze for shorts, open circuits, weak turn-to-turn insulation, unbalances in the coils, and damaged or misconnected commutator risers and equalizers. For the best armature diagnostics, the Baker DX can be used with the Baker ZTX low-impedance test accessory, which enables bar-to-bar testing on most DC armatures. The Baker ZTX lowers the maximum surge test voltage and increases the available surge current for testing very low impedance coils.The Baker DX-15A features integrated ZTX technology built into the instrument.Performing armature tests is easy with the ATF5000 and Baker ZTX low-impedance component test accessorieswww.megger.com                                             51) Requires Winding Resistance option2) Requires Inductance / Capacitance option3) Requires PD (partial discharge) option4) Requires RIC (rotor influence check) option
