Tester for Teleprotection Commands (UTK8)


The tester is measuring and reporting the key parameters of teleprotection commands for various point-to-point and point-to-multipoint distance protection applications, used by electrical power utilities.


The UTK8 is a versatile measurement equipment that allows technicians to check and prove the teleprotection channel performance end to end (up to 8 teleprotection commands at once). Practical appliance of the tester is essential for conducting:
  • Factory Acceptance Tests
  • Commissioning of a teleprotection system
  • Service & Maintenance

The UTK8 is able to test legacy and present-day teleprotection equipment that utilizes binary inputs / outputs for transmission of the commands over:
  • digital telecommunication channel
  • power line carrier
  • microwave links
  • dark fibers

UTK8 features
  • A front panel with big 5-inch TFT color display and functional buttons allow to demonstrate, save into a file or even print the measurement results for further analysis
  • Thanks to intuitive user software tool the operator may carry out the measurements by means of software tool, installed onto maintenance laptop or execute the same directly from the UTK8 front panel
  • There are 8 binary outputs available on UTK8 in order to operate 8 binary inputs of the teleprotection equipment under test
  • Operating the binary inputs of the teleprotection equipment under test driven by the “dry” contacts or substation battery voltage is a great advantage
  • Binary outputs of UTK8 equipped with overcurrent protection
  • 8 binary inputs with the possibility of feeding either from internal DC voltage source or station battery
  • There is additional relay contact available to control the operation of various devices together with the commands transmission. Example: attenuator or noise generator
  • Universal power supply 230 V AC / 220 V DC
  • Built-in device calibration function
  • 0.1 ms accuracy for measurement of command transmission time is now achieved
  • Ability to create, save and load a configuration profile (up to 16 profiles)
  • Archiving the test results using embedded memory of UTK8 is possible
  • Dependability and security measurements


  • Compact and handy design (220x140x40 mm, weight 0.8 kg)

  • UTK8 allows simultaneously testing up to 8 commands
