22 kV Oil-Immersed Distribution Transformer

Overview: A 22 kV oil-immersed distribution transformer is a candidate for networks that use a 22 kV nominal feeder. It is important to distinguish nominal system voltage from the highest voltage for equipment and the required dielectric test levels.

Where this configuration is considered

Potential uses include utility feeders, industrial parks and renewable energy collection networks. Cable entry, surge protection and location-specific ambient conditions should be reviewed with the broader electrical design.

Information to define before quotation

Provide the network one-line diagram, kVA, LV voltage, highest system voltage, frequency, insulation level, tap duty and fault level. Include loss limits, cooling and the purchaser's acceptance-test requirements.

International standards to review

Reference standards may include IEC 60076-1:2011. The applicable editions, clauses, conformity evidence and test scope must be agreed for the final design and destination market. This page does not claim certification or guaranteed compliance for an unspecified product.

A useful question for the technical brief

What equipment voltage and insulation coordination does the 22 kV network specification require?
