The Hydrocal Range

MTE offers a broad range of products and solutions for online gas-in-oil monitoring of transformers (online DGA). With individual and modular system components MTE provides the optimal customer-oriented solutions for utilities, industries and transformer manufacturers. Analysis of the gases dissolved in power transformer oil is recognised as the most useful tool for early detection and diagnosis of incipient faults in transformers. The cost effectiveness of online dissolved gas analysis (DGA) is recognised worldwide.

Early Warnings

Composite or individual analysis of the key fault gases dissolved in power transformer oil for early warning indication and initial fault classification.

The HYDROCAL 1001+

A permanently installed composite gas-in-oil sensor for the analysis of the six dissolved key fault gases Hydrogen (H2), Carbon Monoxide (CO), Methane (CH4), Acetylene (C2H2), Ethylene (C2H4), and Ethane (C2H6). To detect an even wider range of potential transformer faults, the HYDROCAL 1001+ also analyses content of Moisture (H2O) in the transformer oil.

The HYDROCAL 1003 (offshore version available)

An online permanently installed monitoring system for continuous measurement of Moisture in Oil (H2O) and fault gases Hydrogen (H2) and Carbon Monoxide (CO). An increase in Hydrogen is present in nearly every fault of the isolation system of power transformers. Carbon Monoxide is a sign of cellulosic/paper insulation breakdown. With HYDROCAL 1003 monitoring the transformer can maintain a long and trouble-free service life.

Intensive Care

Permanently installed online Dissolved Gas Analysers for the individual analysis of multiple gases and detailed fault classification.

The HYDROCAL 1005 (offshore version available)

A permanently installed multi-gas-in-oil analysis system with transformer monitoring functions. It allows for the individual measurement of Moisture in Oil (H2O) and the key gases Hydrogen (H2), Carbon Monoxide (CO), Acetylene (C2H2) and Ethylene (C2H4) dissolved in transformer oil. This extra data from the HYDROCAL 1005 reduces the amount of maintenance time because the probable cause of any faults will have been established before action takes place.

The HYDROCAL 1008 (offshore version available)

A permanently installed multi-gas-in-oil analysis system with transformer monitoring functions. It allows for the individual measurement of Moisture in Oil (H2O) and the key gases Hydrogen (H2), Carbon Monoxide (CO), Carbon Dioxide (CO2), Methane (CH4), Acetylene (C2H2), Ethylene (C2H4) and Ethane (C2H6) dissolved in transformer oil. The additional monitoring capabilities allow incipient faults to be further pinpointed and anticipatory resources to be applied effectively.

The HYDROCAL 1009 (offshore version available)

A permanently installed multi-gas-in-oil analysis system with transformer monitoring functions. It individually measures, Moisture in Oil (H2O) and the key gases Hydrogen (H2), Carbon Monoxide (CO), Carbon Dioxide (CO2), Methane (CH4), Acetylene (C2H2), Ethylene (C2H4), Ethane (C2H6) and Oxygen (O2) dissolved in transformer oil. The additional monitoring capability of Oxygen allows for the detection of excessive aging or leakages within the sealing of hermetic transformers.

HYDROCAL Series Extension Packages

Transformer Thermal Condition Monitoring

In addition to the fault gas analysis capabilities of the HYDROCAL range it is also possible to monitor the thermal condition of transformers in real-time using an extension package. Utilising the additional i/o ports on the HYDROCAL range it is possible to monitor up to ten external variables. These may include top oil temperature, bottom oil temperature, tap changer oil temperature, ambient temperature, load voltage, load current, oil level and tap changer position.

HYDROCAL MS-7

Complete on-line transformer monitoring extension package including cabinet, cable glands, power supply, circuit breakers, thermal connectors, anti-condensation heater, transducers, connection cable, transmission cable, and wiring diagram.

ZVCM-1001 Bushing monitoring

Continuous measurement of up to six leakage currents, testing of power factor and capacitance values and monitoring of bushing condition, capacitance coupled voltage transformers (CCVTs) and free standing current transformers (CTs).

Multi-Gas-in-Oil Analysis Systems with Transformer Monitoring Functions

In addition to the main HYDROCAL units, MTE also manufactures Multi-Gas-in-Oil analysis systems with transformer monitoring functions. These units are based upon the HYDROCAL 1005 and 1008 units and are designed for multi-gas-in-oil analysis on a bank of three adjacent single-phase transformers.

The HYDROCAL 1005-3/-2/-1

This wall mounted system allows for the measurement of Moisture in Oil (H2O) and the key gases Hydrogen (H2), Carbon Monoxide (CO), Acetylene (C2H2) and Ethylene (C2H4) dissolved in transformer oil.

The HYDROCAL 1008-3/-2/-1

This wall mounted system allows for the measurement of Moisture in Oil (H2O) and the key gases Hydrogen (H2), Carbon Monoxide(CO), Carbon Dioxide (CO2), Methane (CH4), Acetylene (C2H2), Ethylene (C2H4) and Ethane (C2H6) dissolved in transformer oil.

Tap Changer Monitoring

The MTE HYDROTAP is designed for multi-gas DGA analysis on tap changers and transformer tanks.

HYDROTAP

This wall mounted system allows for the measurement of Moisture in Oil (H2O) and the key gases Hydrogen (H2), Carbon Monoxide(CO), Carbon Dioxide (CO2), Methane (CH4), Acetylene (C2H2), Ethylene (C2H4) and Ethane (C2H6) dissolved in transformer oil.
