Improved cast resin dry type transformer short circuit ability
Dry-type transformer short-circuit test problems were analyzed simultaneously proposed to improve the cast resin dry type transformer short-circuit capacity improvement measures. Short circuit test problems high dry-type transformers, low voltage winding their way around the system, and whether pouring classification, and a table of high and low voltage dry-type mcb circuit breaker can be used arbitrarily high and low voltage circuit breakers form of combination. Respect for these combinations will dry type transformer short circuit test problems are summarized below. Dry-type Voltage stabilizer wrapped inspection classified substandard products accounted for about 6%. Symptom is winding displacement, eccentric, and even high and low voltage windings was smooth, counterclockwise rotation.
