The Portable Test Equipment consists of an integrated current and voltage source and electronic reference standard of accuracy class 0,05 % or 0,02%. Device is available in three-phase version PTE 2300 or single phase version PTE 2100.
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
- Capable to test the ratio and burden of CT/PT
