The International Electrotechnical Commission (IEC; French: Commission électrotechnique internationale) is an international standards organization that prepares and publishes international standards for all electrical, electronic and related technologies.
Transformers are the most critical assets of electrical transmission and distribution systems, and their failures could cause power outages, personal and environmental hazards, and expensive rerouting or purchase of power from other suppliers. Identifying a transformer which is near failure can allow it to be replaced under controlled ...
However, a transformer may include a tap changer on each winding if there are advantages to do so. For example, in power distribution networks, a large step-down transformer may have an off-load tap changer on the primary winding and an on load automatic tap changer on the secondary winding or windings. The high voltage tap is set to match long ...
The commissioning plan is modified as the commissioning process progresses throughout the design, construction, and final acceptance of the facility. The functional performance test procedures are typically developed by the CxP with assistance of the trade contractors, vendors, and manufacturers based on the design engineer's contract documents.

A delta-wye transformer is a type of three-phase electric power transformer design that employs delta-connected windings on its primary and wye/star connected windings on its secondary. A neutral wire can be provided on wye output side. It can be a single three-phase transformer, or built from three independent single-phase units.
Three-phase HV/MV power transformers, located in distribution substations, are the most common source of supply for distribution networks, and type of grounding of their neutral determines the earthing system. There are five types of neutral earthing: [26] Solid-earthed neutral; Unearthed neutral; Resistance-earthed neutral. Low-resistance earthing
