Instrument transformers are specialized electrical instruments used to create precise copies or replicas of high voltages and currents. They include three major classes of dielectric material: liquid-insulated transformers, which are thermally efficient and durable; SF6 gas-insulated transformers, which provide compactness for superior performance; and solid dielectrics, whose increasing popularity is attributable to their environmentally friendly nature and easy maintenance. As per enclosures, instrument transformers can be categorized based on whether they are installed indoors within switchgear rooms and substations or outdoors as the bulk of utility infrastructure grids. The voltage rating can go from distribution voltage all the way up to sub-transmission, high, extra-high, and ultra-high transmission voltage. Instrument transformers can be employed in bushings of transformers and circuit breakers, switchgear equipment, relaying, metering and protection, and primary metering equipment.
The pressure that this market has is regulatory. The SF6 gas-insulated instrument transformers have features that cannot be matched by any other type of liquid or solid transformers when it comes to high voltages. However, the SF6 gas is a highly effective greenhouse gas that is progressively being regulated in Europe and internationally. This is why firms such as ABB, Schneider Electric, and GE are developing new transformer technologies without the use of SF6 gas. However, since this is a highly challenging task, it requires substantial investment in terms of time and money. This presents an immense business opportunity for firms that take the lead in developing SF6-free instrument transformers.
In January 2024, ABB introduced an AI-powered instrument transformer monitoring system designed to enhance power efficiency and reduce maintenance costs, integrating real-time grid monitoring into its medium-voltage transformer portfolio.
