Baker Awa-Iv Instrument Overview - Megger Baker AWA-IV User Manual

2 — Baker AWA-IV Instrument Overview
The Baker AWA-IV automatically performs repeatable, user-programmable tests to thoroughly assess the strength of
a motor's insulation and circuit. The analyzer can be programmed to perform a specific set of insulation tests in the
shop or office, then used as programmed in the field. The AWA-IV is also used to assure quality of motor rebuilds or
new production motors before they are placed into service.
The Baker AWA-IV features an intuitive, touch-screen user interface. It delivers accurate repeatable results,
performing a comprehensive set of both high- and low-voltage tests. Results are presented in simple, easy-to-
understand graphs and reports that give motor maintenance professionals the information they need to minimize
costs and unplanned downtime.
The ability to apply identical tests to a given motor over a long period allows trends to be analyzed, revealing the
degradation of insulation over the motor's lifetime. This allows maintenance professionals to predict motor failure
and replacement planning.
The AWA-IV offers computer control and waveform monitoring. The analyzer's embedded computer conducts the
tests, stores the results, and continuously monitors voltage levels while testing. If the analyzer 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.
The AWA-IV's benefits can be extended to low-impedance coils—such as armatures—through the use of the Baker
ZTX low impedance coil accessory. The ZTX allows the AWA-IV to apply surge tests to coils that require higher
currents.
