MTE HYDROTAP – Tap Changer Monitoring Online Individual Dissolved Gas Analysis – 7 Gases 7 Moisture

As Hydrogen (H2) is involved in nearly every fault of the isolation system of power transformers and Carbon Monoxide (CO) / Carbon Dioxide (CO2) is a sign of degradation of the cellulosic / paper isolation the presence and increase of Acetylene (C2H2), Methane (CH4), Ethylene (C2H4) and Ethane (C2H6) further classifies the nature of a fault as overheating, partial discharge or high energy arcing.

Datasheet

MTE HYDROTAP – Tap Changer Monitoring Online Individual Dissolved Gas Analysis – 7 Gases 7 Moisture

Description

The device can serve as a compact transformer monitoring system by the integration / connection of other sensors present on a transformer via its analogue inputs:

  • 4 analogue inputs 0/4-20mADC
  • 6 analogue inputs 0/4-20mADC +20% / 0-80 VAC +20%

Configurable by jumpers It is further equipped with digital outputs for the transmission of
alarms or the execution of control functions (e. g. control of a cooling system of a transformer):

  • 8 digital relay outputs
  • 5 digital optocoupler outputs
