VLF test 0.1 Hz · Sheath fault test

  • Commissioning test after new construction · extension · repair

Why does a commissioning check have to be carried out?

  • Compliance with legal, technical and operational regulations
  • Tests according to German BGV A3
  • DIN VDE 0276 Part 620 and Part 621 · Din VDE 0105
  • Avoidance of accident hazards

Quality control !

  • Increase of operational and supply security
  • Quality control of assembly & material
  • Avoidance of malfunctions and failures
  • Securing the network quality
  • Value retention of your plant

Exam options & types :

  • VLF sine 1 … 42.5 kV (60 kV peak) 0.1 Hz
  • VLF Square-wave voltage 1 … 60 kV
  • Gas-insulated (SF6) & air-insulated systems

Sheath fault testing

  • Quality control of installation & material

Cable location · Working with sound transmitter / receiver

Location of :

  • Buried cables · pipes · pipes
  • ≤36 kV Medium voltage · Low voltage · Telecommunications, telecontrol, cable television and communication lines · Empty pipes · Metal pipes · Pipe ends · Transfer pipes
  • Path Determination · Depth determination · Plan correction · Plan completion
  • As a rule, the lines can remain in operation to determine the route

cable selection

  • buried cable · Cable whose affiliation can not be determined unambiguously, by design or directly

phasing

  • Preliminary test of buried cables · Overhead line · in earthed condition · whose phase assignment is not known · on sockets and cable ends
  • Check · before switching on switchgear

error measurements

  • buried cables · line whose fault is earth-sensitive
  • Sheath fault -Check, Pre-location and post-location (fine location)

earth Testers

  • of new and existing earth electrodes

I am constantly trying to expand the measurement program bezw. to complete
