MICAMAXX®pda


Manufacturer: Qualitrol show products

Easy-to-use Partial Discharge Monitoring System
MICAMAXX®pda is a partial discharge trending system comprising an on-line monitoring unit and PD transducers, which are fitted to the machine as a permanent installation to enable continuous on-line monitoring of the insulation system. Partial discharge sensors, such as coupling capacitors and high frequency current transformers are available for all HV-machine rated currents and voltages. And of course, they can be installed in hazardous environments

Description

Corrective action prompted by early warning ofcritical winding condition can mean the difference between a brief shutdown for minor repairs and a major over-haul involving weeks, or even months of costly downtime!
MICAMAXX®pda is PD Tech Power Engineering’s state-of-the-art solution for on-line monitoring of high voltage rotating machines, ensuring greater availability of plant assets

The Solution
Partial discharge condition monitoring provides an early warning of critical problems in the stator winding and the HV-system, so that corrective measures can be taken before costly damages occur. Catastrophic failures will eventually develop as a result of undetected electrical defects. In this case a new stator winding is likely required and lead-times for replacement can be lengthy.
Stator Winding and High Voltage System
The stator winding and the high voltage auxiliaries are monitored by PD Tech Power Engineering’s MICAMAXX®pda technology.
As Easy as Temperature Monitoring!
The MICAMAXX®pda is a Partial Discharge trending system with an integrated 4…20mA Interface and Alarm Contacts. The main application is to convert the global Partial Discharge activity on electrical machines to a stabilized 4…20mA analogue signal which can be integrated into an existing machine control or data logging system. This makes the Partial Discharge monitoring as easy as temperature monitoring.
Solution for all HV Rotating Machines
MICAMAXX®pda is a partial discharge trending system comprising an on-line monitoring unit and PD transducers, which are fitted to the machine as a permanent installation to enable continuous on-line monitoring of the insulation system.

Applications

  • The MICAMAXX®pda is working in industrial environments such as the gas and oil industry in on- and off-shore environments, polymer factories, steel mills, as well as on generators and motors. 
  • PD Tech Power Engineering AG has developed couplers and systems with the respective ATEX certificates in order to allow a safe application.
  • The MICAMAXX®pda provides utilities with extra safety. Hydro and turbine generators of any power and voltage ratings are monitored with MICAMAXX®pda. This includes pump storage, gas turbine sets, steam turbines, emergency pumps and many more.
