Elektros įrenginių bandymų ir testavimo įranga


Switch module

The external module STCS allows performing automatically the following PT tests: ratio per tap; winding resistance; OLTC dynamic test. The connection to the transformer under test, to STS and to the measurement taps is performed just once; then, all transformer tests are performed without interruptions.

  • Additional module of STS 5000 and STS 4000
  • Inputs from STS: 300 V AC or 6 A DC
  • Tap Changer Up / Down: 240V AC or 110V DC
  • Outputs to STS measurements: 300 V AC or DC and 10 V DC
