  Description:

Safety of transformers, reactors, power supply units and combinations thereof - Part 2-23: Particular requirements and tests for transformers and power supply units for construction sites

  Purpose

This part of IEC 61558 deals with the safety of transformers for construction sites and power supply units incorporating transformers for construction sites. Transformers incorporating electronic circuits are also covered by this standard. NOTE 1 Safety includes electrical, thermal and mechanical aspects. Unless otherwise specified, from here onward, the term transformer covers transformers for construction sites and power supply units incorporating transformers for construction sites. This part is applicable to stationary or portable, single-phase or polyphase, air-cooled (natural or forced) independent or associated transformers, being isolating or safety isolating dry-type transformers for the use on construction sites. The windings may be encapsulated or non-encapsulated. The rated supply voltage does not exceed 1 000 V a.c., and the rated supply frequency and the internal operating frequencies do not exceed 500 Hz. This standard used in combination with Part 2-16 for Switch mode power supply units (SMPS) is also applicable to power supplies with internal operating frequencies higher than 500 Hz. Where the two requirements are in conflict the most severe take precedence The rated output does not exceed: - 25 kVA for single-phase transformers; - 40 kVA for poly-phase transformers. This part is applicable to transformers without limitation of the rated output subject to an agreement between the purchaser and the manufacturer.
