Vaisala Widens MHT410 Transmitter’s Measuring Capabilities to Ester Insulation Fluids

Vaisala, a global leader in environmental and industrial measurements, expands the coverage of its MHT410 Transmitter. The transmitter provides now reliable measurements also in transformers that use natural or synthetic ester oils. 

Vaisala’s Moisture, Hydrogen and Temperature Transmitter MHT410 for Transformer Oil is an ideal choice for power transformer operators wishing to reduce the probability of outages and prolonging the lifecycle of their transformer fleet. MHT410 is installed directly into the oil flow of the transformer, where it monitors moisture, hydrogen as well as temperature. Thus the instrument reduces the amount of manual work and enables operators to keep up do date of their transformers’ condition in real-time.

“Previously, MHT410’s measurement was limited to transformers filled with mineral oils – the most common oil type in transformers. The expansion to ester fluids widens Vaisala’s measuring capabilities regarding transformer condition monitoring. The accuracy and reliability of the measurements are at the very core of Vaisala’s business, as is the case also with this new expansion,” explains Product Manager Teemu Hanninen, Industrial Measurements, Vaisala.

One of the differences between mineral oil and ester fluids is that they have different gas and water solubility. For this reason, when customers now place an order for MHT410, they first need to identify, which oil type their transformers are filled with. Based on this information, the product is customized with appropriate parameters for each customer’s needs.
