IEC 60947-6-1 Low Voltage Switchgear and Control Equipment - Part 6-1: Multifunction Hardware - Transfer Switchgear Testing

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of IEC 60947-6-1 testing. IEC 60947-6-1 applies to transfer switching equipment (TSE) to be used in power systems to ensure continuity of supply and energy management of the installation by transferring a load between power supply sources.

This edition includes the following important technical changes from the previous edition:

• Clarification of scope and purpose;
• Clarification of terms and definitions;
• Removal of unnecessary definitions;
• Changing properties;
• Changing the definitions of usage categories;
• The introduction of new marking requirements;
• Addition of new requirements for gaps and leakage distances;
• Addition of new requirements and tests for mechanical and electrical interlocks;
• Clarifying transfer sequences;
• Changing the requirements for rated short-time withstand currents;
• Modification of new requirements for electromagnetic compatibility;
• Description of performance requirements for CB type TSE in accordance with the requirements specified in IEC 60947-2;
• Critical load current performance of DC rated equipment.

Availability of power in low voltage electrical installations plays an increasing role in modern society. In fact, this requirement is an essential feature for the creation of economically and functionally efficient plants. A system that can switch a load from one source to another safely and with minimal disturbance to the load minimizes problems caused by faulty conditions in the normal supply.

Transfer switching is usually accomplished by implementing a transfer function within the electrical installation, but this critical function can be inappropriately designed. Using a TSE that follows the requirements of this document ensures the safety and performance of the transfer function necessary to achieve the objectives listed above.
