Current-measuring-transformers

TF 100 Tr/Th-Pk

TF 100 Tr/Th-Pk

Protects measuring transformers; lightning and surge voltage protector for 5 A cores in current transformers.

  • extremely high impulse and AC current resistivity
  • lightning impulse current discharge capability 100 kA (10/350 µs)
  • no blow-out vents, therefore no safety distances required for installation
  • high insulation resistance Riso > 10 GΩ
  • very long service life
  • optional potential free remote signal contact (PK)

TF 500 Tr

TF 500 Tr

Electrical isolation of grounds and system components

  • very high surge and alternating current discharge capability
  • surge current 100 kA (10/350 µs)
  • spark gap without blow-out vent, therefore no security distances required
  • spark-over voltage independent of air-pressure and humidity
  • very long service life
