Engineering Services

PT. MESINDO TEKNINESIA in joint facility with Power Lab Inc. Canada Offer Engineering services such as :
 
  • Design an optimized PD testing system based on the client’s requirement and application;
  • Installation and commissioning of the partial discharge system;
  • Perform partial discharge testing;
  • Interpretation and analysis of PD testing data from various PD measurement systems;


Partial discharge (PD) testing is a recognized tool to diagnose stator insulation deterioration and the other related problems. The tests can be performed under the on-line condition (when a machine is running) or the off-line condition (when a machine is stand still). On-line PD testing can give early warning of potential machine failures and provide machine condition information for predictive maintenance.

PT. MESINDO TEKNINESIA in joint facilities with Powertech provides both on-line and off-line PD test services and insulation condition assessment of hydro-generators, turbo-generators and motors operating above 3.3 kV. The HV couplers are connected to the machine terminals to detect partial discharges from the stator winding. A computer-controlled instrument measures PD signals detected by the HV couplers. Our PD specialist then analyzes the test data to provide an insulation diagnostics report. The nature, type, region, and severity of PD activity can be identified as follows through data analysis:

Benefits of partial discharge test for generators and motors  :

  • Identify sources of potential catastrophic failures
  • Extend maintenance outage intervals
  • Extend the lifetime of stator windings
  • Confirm effectiveness of repairs
  • Decide maintenance priority of a group of machines.
