Abstract

This chapter described the pre-commissioning process, i.e., all those checks and tests which take place after installation and before first energization. The chapter includes background information on the aims of pre-commissioning, and especially its possible impact on safety. This chapter includes detailed descriptions of visual inspection after installation; functional checks on the transformer or reactor, coolers, tap-changer, control cabinet, and other associated equipment. This chapter includes a detailed description of various electrical tests made after installation, excluding high voltage tests requiring special equipment which are the subject of a separate short chapter. This chapter also includes a detailed description of liquid tests required after filling at site, and before first energization.
