The PDTracII instrument performs automated, continuous Partial Discharge measurements for motors, generators, switchgear and dry-type transformers. The PDTracII instrument provides maintenance professionals with an opportunity to continuously monitor equipment for insulation breakdown. This instrument will automate measurements and store recorded data for up to 2 years. The PDTrac instrument includes Sensor Input Modules, Alarm Output and can be supplied with optional Analog Signal Output Module. The PDTracII instrument can be completely controlled from a remote location and contains communication options including USB or Ethernet TCP/IP. Plant personnel can configure the unit, test the machines and receive alarm notifications from their office PC. The optional Modbus interface allows users to integrate partial discharge (PD) data from continuous on-line PD monitoring instruments, through a LAN, into external applications for alarming, displaying and/or trending.

PDAlert instrument measures stator winding partial discharges caused by Inverter Fed Drives (IFDs). IFDs create thousands of fast rise time voltage surges per second. These surges sometimes lead to stator failure. The PDAlert instrument is the first on-line device which allows non-specialists to easily measure PD in each phase, under fast rise time surges. When combined with certain surge testers, PDAlert instrument also enables users to determine PD inception and extinction voltage off-line. The PDAlert instrument outputs analog signals to display the PD on a high speed digital oscilloscope.

Electromagnetic Core Imperfection Detection (EL CID) testing is accepted world-wide for reliable and safe detection of stator core inter-laminar faults (CIGRE, 2004). Originally developed by the CEGB in England, the EL CID Evolution is a third generation instrument that is proven, reliable and easy to use. The EL CID Evolution tests the condition of a stator core in less time and with fewer resources than the earlier EL CID models. The EL CID instrument can be used to test turbo-generators, hydro-generators, and large motors.
