The Baker AWA-IV automatically performs repeatable, user-programmable tests to thoroughly assess the strength of a motor’s insulation and circuit. In fact, it is the only high-voltage test instrument that a user can program to perform a specific set of insulation tests prior to being in the field, and then use 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 EXP4000 is a powerful tool, designed for site use, to analyse the motor running under its normal load. It tracks multiple data types to identify trends that indicate potential problems. Voltage and current are measured and a series of parameters are then calculated, including power quality, rotor bar condition, % load, % operating efficiency, average torque value, torque ripple showing variation within process, monitoring of start-up transients (volts, current and torque), and much more.
Defects in medium and high voltage systems not only require costly repairs, but also can lead to failures of entire network sections with corresponding consequences. Therefore, it is in the interest of all network operators to recognize signs of impending defects as early as possible and to be able to take appropriate countermeasures on time.
With the PD Scan, Megger offers a lightweight, robust and portable PD scanner that can quickly inspect various type of equipment for partial discharge signals.
