The discharge procedure for a dry-type transformer after a power outage is as follows:

Monitors load current using current transformers and relays to prevent transformer damage due to prolonged overload.

Dry-type transformers can be stored outdoors, but environmental conditions and protective measures must be taken.

**Fixed Power Distribution Cabinets:** Typical models include the GGD and GCK series.

Power distribution cabinets, as core equipment in modern power distribution systems, are widely used in industrial, commercial, and public facilities.

A power distribution cabinet typically includes a main switch, circuit breakers, contactors, transformers, and controllers.

Voltage regulation depends on the transformer's design and configuration, and is typically achieved through tap changers or off-load voltage regulator

Dry-type transformers are widely used in industrial production, such as manufacturing and petrochemical industries, for voltage transformation and sta

Includes high-voltage and low-voltage side coils, typically made of copper foil or copper busbars to reduce losses and improve conduction efficiency.

Check for abnormal sounds and vibrations.

Short-circuit the transformer's "input" and "output" terminals and test their insulation resistance to ground using a megohmmeter.
