MTE HYDROCAL 1005-3/-2/-1 Online Individual Dissolved Gas Analysis – 4 Gases & Moisture

The HYDROCAL 1005-3/-2/-1 is designed for multi-gas-in-oil analysis on a bank of three adjacent single phase transformers. This wall-mounted system allows for the individual measurement of Moisture (H2O) and the key gases Hydrogen (H2), Carbon Monoxide (CO), Acetylene (C2H2) and Ethylene (C2H4) dissolved in transformer oil utilising a sampling system that samples oil from each tank via three separate oil channels.

MTE HYDROCAL 1005-3/-2/-1 Online Individual Dissolved Gas Analysis – 4 Gases & Moisture

Description

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

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

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

  • 5 digital relay outputs
  • 5 digital optocoupler outputs
