MTE HYDROCAL 1008-3/-2/-1 Multi-Transformer Online Individual Dissolved Gas Analysis – 7 Gases & Moisture

The HYDROCAL 1008-3/-2/-1 is designed for multi-gas-in-oil analysis on a bank of up to three single adjacent phase transformers. This wall mounted system allows the individual measurement of Moisture (H2O) and the key gases Hydrogen (H2), Carbon Monoxide (CO), Carbon Dioxide (CO2), Methane (CH4), Acetylene (C2H2), Ethylene (C2H4) and Ethane (C2H6) dissolved in the transformer oil utilising a smart sampling system that samples oil from each tank via three separate oil channels.

Datasheet

MTE HYDROCAL 1008-3/-2/-1 Multi-Transformer Online Individual Dissolved Gas Analysis – 7 Gases & Moisture

Description

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.

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
