How to discover circuit errors in meter installations

Yearly financial losses to energy suppliers caused by connection errors in meter installations are not to be neglected. There are many possibilities to make incorrect connections during installation. Many times, installation faults are rarely discovered at the time of billing and sometimes not recognised for many years. This results in considerable losses to energy suppliers. During the time of liberalisation in the energy market the meaning of correct energy billing becomes even more important, especially because more parties are involved in this process. This paper shows how with the help of a modern, inexpensive, lightweight and easy to operate portable meter test equipment (MTE) the errors can be detected early, during installation, resulting in cost efficiency and less complicated service
