Metering transformer

A metering transformer, also known as an instrument transformer, can be used where the circuit current is too high to deploy measuring or metering instruments directly. The metering transformer reduces the current to a level that those instruments can safely handle. It does so in a predictable and proportionate way, allowing for the accurate measurement of the total current to be deduced from the reduced current. These transformers isolate the metering instruments from a potentially damaging level of voltage and they are often used in the power industry in protective relays.

The SADTEM metering transformer range

SADTEM has been in business for more than 80 years and each metering transformer that the company builds benefits from this incredible depth of experience and technical knowledge. The company is still a private and independent firm and is free to deploy its resources for the ultimate benefit of its customers. Based in northern France in the town of Douai, the company has specialised in the production of protection and metering transformers since 1929 and produces units both for outdoor and indoor application. The company has built up an international reputation for the quality of its products and currently supplies customers in more than 80 different countries.

Ensuring the quality of your metering transformer

SADTEM’s experience means that the company understands what it takes to consistently produce the best quality of metering transformer on the market. The company’s quality system is certified to ISO 9001 standard and it is further developed to identify and eliminate any possibility of component fault. SADTEM laboratories are well equipped to complete the standard test types as required by international standards. These include temperature rise tests, impulse voltage tests, frequency withstand tests, ageing and climatic tests. SADTEM supplements these quality procedures with a system of internal controls which are designed to guarantee the quality of each piece of raw material before it even enters the production line.

Flexibility for your metering transformer requirements

SADTEM has a modern, computerised production facility that is situated in-house. This gives the company precise control over its manufacturing processes and allows it to respond quickly to customer demand. The company has more than 50 years of experience in casting processes and uses, ensuring that SADTEM always has the correct metering transformer for the job in hand. This flexibility means that SADTEM can supply orders for many thousands of units, while still being able to deliver smaller, custom orders.
