Three Phase Oil Immersed Small Substation Transformer for Industry

QXG Transformer

Substation transformers are generally oil-immersed. Mineral oil, vegetable oil or siliceous transformer oil. Widely used in various utility or small industrial applications. Construction standards are generally IEEE, CSA standards. The primary voltage of transformers in substations is usually a minimum of 2.4 kV and a maximum of 69 kV, which is based on the IEEE standard. The minimum capacity is 150kVA to the maximum 20MVA, and the secondary voltage can also be a minimum voltage of 0.6KV and a maximum voltage rating of 35kV.

IEEE Test

First consider the resistance test, polarity test, phase relationship test, ratio test, no-load loss test, load loss test, and suitability temperature rise test, dielectric test. At the same time, in order to ensure the safety of the test and the damage to the transformer, the voltage part related to the current should be tested first.

In addition, the lightning test is not a mandatory test, especially under the condition of small capacity and voltage, a lightning test may cause catastrophic loss to the transformer, we can consider the sampling test under the conditions, there are low frequency tests, induced voltage tests, etc.
