Combined transformers

Combined transformers can be an extremely useful option in environments where available space is at a premium. This type of transformer is actually two transformers in one, with a voltage transformer and a current transformer cast in a single body. The use of such transformers can also save time in installation and save money in fixing hardware. SADTEM offers two types of combined transformers. The first type is a single phase model in moulded cycloaliphatic resin. The second option is a metallised structure type in single or three phases. All SADTEM transformers of this type are outdoor models. The use of these transformers is limited by their size and they are usually deployed in revenue metering situations.

SADTEM’s in-house production systems also allow the company to respond effectively to customer requirements, producing volume orders and also working on one-off custom design projects.

A quality-led environment for combined transformers

The control that SADTEM is able to exert over its production capabilities is also important in maintaining effective quality control systems. This focus on quality has resulted in the company achieving ISO 9001 status. The company also enjoys its own laboratory facilities and these are equipped to carry out a number of tests to international standards. Future SADTEM combined transformers are constantly being redesigned according to knowledge gained in the company’s research and development activities, while today’s units benefit from testing throughout the production process.
