Portable test equipment PTE

The Portable Test Equipment consists of an integrated three-phase current and voltage source and a three-phase electronic reference standard of accuracy class 0.05 % or 0.02 %.

Properties

  • Laboratory and on-site meter measurements
  • Easy evaluation of meters under precise load conditions, using the built-in compact current and voltage source
  • Testing of meters with closed I-P links
  • Automatic operation with predefined load points without the need for an external computer
  • Each source channel can be programmed with user defined harmonic content or standardized signal test shapes
  • Each source channel can be modulated with programmable Ripple control telegram
  • Independent generation of single or three-phase loading conditions for testing, calibration and verification of meters
  • Active, reactive and apparent energy measurement for three phase, 3 or 4-wire, systems with integrated error calculator and pulse output
