UK Design and manufacture of wideband current measurement transformers and wideband voltage measurement transformers

Lilco designs and manufactures custom current measurement transformers for a number of clients, ranging from research institutions to OEMs. These can be low volume specials, typically five or less, to production runs requiring scheduled delivery over many months.


Customisation can be in the form of optimisation of electrical parameters if a standard part does not fit your requirement, or we can design a transformer and package to fit in with your electrical and mechanical requirements. We work with your engineering to finalise the product.

Some examples of customised products:
