IEC EN 62310-2 Static Transfer Systems (STS) - Part 2: Standard Test for Electromagnetic Compatibility (EMC) Requirements

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of IEC EN 62310-2 testing. It is applied to stand-alone operation ac static transmission systems (STS), which aim to ensure continuity of load supply through controlled transmission from two or more independent ac sources.

The IEC EN 62310 series also includes information for the general integration of STS and accessories into the AC power network. Applies to systems up to 1000 V ac, intended for use in single-phase, phase-phase or three-phase applications.

This part of IEC EN 62310 takes precedence over all aspects of the general standards and no additional testing is required.

The requirements have been chosen to provide an adequate level of Electromagnetic Compatibility (EMC) for STS in public and industrial locations. However, these levels cannot cover extreme situations that can occur anywhere, but they are extremely unlikely to occur.

It takes into account the different test conditions required to cover the physical dimensions and power ratings of the STS.

An STS, whether presented as a unit or a group of units, must meet the relevant requirements of this part of IEC 62310 as a stand-alone product. The EMC phenomenon produced by any supply or load connected to the input or output of the STS equipment will not be considered.

This standard does not apply to:

• Switching devices source for DC;
• Single source systems;
• Transfer systems using only electromechanical switching devices, intended for use in emergency power systems with the interruption of the load supply during transfer;
• Automatic switching devices integrated into Uninterruptible Power Systems (UPS) within the scope of the IEC 62040 series.

For general definitions, the terms and definitions given in IEC EN 62310-1 and the terms and definitions related to EMC and related events in IEC 60050 (161) apply.

Emission limits represent basic electromagnetic requirements selected by test methods to ensure that disturbances produced by STS during normal operation do not reach a level that could prevent other devices from operating normally as programmed.
