    Hydrogen and Moisture Analyzer for Transformer Oil Monitoring TOR-2

    Hydrogen and Moisture Analyzer for Transformer Oil Monitoring

    The TOR-2 transformer oil express-tester is designed to determine the moisture and hydrogen content in mineral insulating oils and ether based insulating oils. Moisture and hydrogen content is measured in parts per million (ppm).

    Knowing the content of hydrogen and moisture in the oil, as well as the rate of parameter change, it is possible to detect problems developing in the transformer in advance and to take timely measures to prevent damage to the transformer.

    Moisture measurement

    The device measures the activity of the water using a capacitance sensor, which ensures stability over time and contamination resistance. The oil temperature is also measured. The moisture content is calculated from these measurements.

    Hydrogen measurement

    A highly selective solid state sensor immersed directly in oil is used to measure hydrogen content. The sensor ensures accuracy and reliability of direct measurements. Low solubility of hydrogen in oil and its high diffusion capacity make it easier to detect at low concentrations, so a problem in the transformer can be identified early.
