Testing LV transfer switching for continuity of power supply

Testing LV transfer switching for continuity of power supply
08 . Feb . 2022

Power outages can occur and, when they do, they could serious consequences, even in high reliability distribution networks, leading to major incidents and losses on critical applications like hospitals, server rooms, production machines.

To prevent this, aside from relying on UPS (Uninterruptible Power supply) , choosing and using correctly a Transfer Switching Equipment (TSE) is highly recommended.

A transfer switch equipment is an electrical switch that switches a load between two sources. Some transfer switches are manual, in that an operator activates the transfer by throwing a switch, while others are automatic and are triggered when they sense one of the sources has lost or gained power .

Key factors motivating customers to use Transfer Switch Equipment include increasing number of electronic devices , the new demands of electric vehicles , the evolution of the electricity market with a greater number of renewable energy sources.

The performance of Transfer Switching Equipment is defined by TSE manufacturers and, by the 3 rd edition of IEC60947-6-1 published in 2021, which includes:

  • manually operated transfer switching equipment ( MTSE ).
  • remotely operated transfer switching equipment ( RTSE ).
  • automatic transfer switching equipment ( ATSE ), including the controller.

In this respect, KEMA Labs Low voltage in Berlin (Germany), thanks to its long experience in testing of low voltage equipment and under its accreditation scope, can perform all the tests sequences required by the standard and grant to the manufacturers the highest technical level.
