Multifunctional Primary Test System for Substation Commissioning and Maintenance

OVERVIEW

This world-wide unique system allows for automated testing of power transformers, CTs, VTs, resistance testing, and more. Providing up to 800 A (or 2000 A with current booster) and 2000 V with a frequency range of 10-400 Hz, it also comes complete with an integrated PC.

Its software routines test a wide range of substation equipment, and automatically create customizable reports. The compact design (29 kg / 64 lbs) and the innovative software save testing time and minimize transportation costs.

Analog voltages and currents can be measured with very high precision. Its O meters offer ranges from µO to kO to allow for a wide variety of applications.

Testing of unconventional equipment, such as Rogowski Coils or current sensors completes the spectrum. Additional aplications can be added with the use of flexible accessories to include tangent delta / power factor testing and primary measurements of power system equipment.

LIGHTWEIGHT
29 kg / 64 lbs

  • Less than one fourth the weight of equivalent conventional equipment
  • Lower transportation costs saves money
  • Easier handling reduces manpower needs
  • Low weight reduces injury potential

ONE TEST UNIT FOR MULTIPLE USES

  • Replaces need for multiple test sets (e.g. high current and voltage sources, µO meter)
  • Saves time by eliminating need for multiple training
  • User-friendly interface reduces training time to one day

AUTOMATED TESTING AND REPORTING

  • Prepare test plans ahead of time in office (saves time in field testing phase)
  • Set up test once, push button to start (saves testing time)
  • Results automatically saved (saves time and reduces errors by eliminating manual recording of data)
  • Automatic report generation (saves time by eliminating manual report writing; accelerates project completion)
  • Print reports via external

PC SAFETY FEATURES

  • Emergency shut off button
  • Safety key lock (block unauthorized use)
  • Overvoltage protection on all inputs and outputs

PREPARED FOR THE FUTURE

  • Able to test unconventional equipment like Rogowski Coils or current sensors
  • Unit accessible in a network or with direct PC connection via standard internet protocols
  • Maximum flexibility for future enhancements by using DSPs for signal generation and switched mode amplifier technique
