Power quality monitoring

K7DD-PQM detects failures of various motor parts using the feature values of captured power quality

The K7DD-PQM advanced motor condition monitoring device makes it possible to identify failure modes and defect parts of motor equipment while rapidly translating power quality such as motor current and voltage into data. This enables scheduled maintenance activities with real-time condition monitoring of motors that frequently change speed, which were difficult to identify abnormalities so far. And simplified condition monitoring device parameter configuration process is contributed to understand K7DD-PQM installation efficiency quickly.

  • Samples up to 6 channels (current and voltage) simultaneously at 2.5μs
  • Abnormalities on the motor & rotating shaft & load side can be judged individually
  • SW tool minimize analysis skills requirement

Features

Measure the power quality of motors

The K7DD samples up to 6 channels simultaneously at 2.5μs. By operating 3-phase power line current/voltage every 50 ms, it detects over 140 types of feature values.

Monitors servo and induction motors

A variety of factors may cause motor equipment failure. K7DD makes it possible to monitor these failure modes individually and suggest subsequent actions to be taken by maintenance staff depending on the condition.

Three wiring methods possible

K7DD can measure both the voltage and current or only the current of power lines that drive motors, valves, and other measurement targets.

Simple retrofitting

Using clouds, data servers, or other IT devices not only requires system-building skill and coordination with IT administrators, but also necessitates specialist installation work. The K7DD do not require special skills, and it can be retrofitted with minimal installation workload. After installation, you can check abnormal conditions from the K7DD display screen directly.

 

Reduces inspection workload

 

As said K7DD provide more than 140 types of feature values, however, the handling of these data requires extremely advanced data analysis skills. With the K7DD, these analyses are supported to enable rapid startup.
