Description

Megger BAKER AWA-IV/12 12kV Static Electric Motor Analyzer Producgt Highlights Analyzes the Condition of the Insulation Systems in Motors and Generators, as Well as Motor Circuit Condition such as Imbalances Determines the Condition of Turn-to-Turn, Phase-to-Phase and Ground-Wall Insulation Using Standards-Based, Low- and High-Voltage Tests User-Programmable Test Sequence Automation for Repeatability and Trends Over Time Centralized Data Analysis Allows Site Managers to Monitor Asset Condition Across Multiple Testers and Routes Tests Include: Winding Resistance, Insulation Resistance, Dielectric Analysis (DA), Polarization Index (PI), DC Step-Voltage, DC Continuous Ramped, DC Hipot, Surge Each Unit Includes Power cord USB flash drive with desktop software User manual (on USB flash drive) Test leads Keyboard with integrated mouse Designed for fast, reliable, automated testing The SKF Static Motor Analyzer - Baker AWA-IV is designed to perform automated sequences of a user-selected array of motor insulation tests. The analyzer's embedded computer conducts the tests, stores the results and continuously monitors voltage levels while testing. If the computer detects a weakness in the insulation during a given test, the test is interrupted, the operator is alerted and all test parameters at the time of the interruption are reported. This instrument performs this automated operation in microseconds, and with a higher degree of precision and safety than can be achieved through manual test methods. Pre-programmed in the office and implemented in the field The Baker AWA-IV is the only high-voltage tester that can be programmed to perform a specific set of insulation tests by a user prior to being in the field, then used as programmed in the field. A user's work orders or routes often define which motors to test, the order of execution and parameters for each test, such as voltages, duration and pass-fail limits. Operators can program the unit to conduct tests in the field simply by connecting to the analyzer. This allows users to minimize time and effort involved with repeat maintenance test sequences performed manually, and improves reliability of testing procedures. Save testing results When testing is complete, results can be saved as part of each motor's permanent test record. This type of documentation is critical to successful reliability programmes. With the AWAIV, test results are collected, stored, recalled and managed using a standard Microsoft Access® relational database format. The Baker AWA-IV produces .rtf type test data files, so a variety of desktop computer word processing software programmes can be used. These database files make it easy to transfer information to common maintenance management software or other database tools. MS Access® is ODBC compliant. Incorporates advanced inter-turn capabilities in a field portable instrument Computer control and waveform monitoring are enhancements above manually controlled instruments. As with the DC HiPot test, the Baker AWA-IV begins surge generation at low voltage. Each pulse applied to the winding is digitized and the resultant waveform is compared to previous waveforms to detect any signs of turn-to-turn weaknesses. Comparison is done by the patented Pulse to Pulse Error Area Ration (PP-EAR) technique. This method is sensitive to less than a one percent variance between coils. In addition, shorts among windings in parallel can be located, something that was never possible before by visually comparing waveforms. With the Baker AWA-IV, fewer pulses are applied to the winding, reducing the power required to perform the surge test. Since each and every pulse is analyzed, it becomes the new reference waveform as test voltage is increased up to the specific withstand level. If no turn-to-turn weakness is detected, the final pulse waveform is stored as the reference waveform for all subsequent tests.
