Transformer Services - GE Grid Solutions transformers are critical for ensuring a sustainable supply of power to prevent outages. With the loss of insulation being irrecoverable, transformer failure risk can be minimized only if oil quality is maintained, moisture is controlled, temperatures are managed, incipient faults are detected and corrected, and an overhaul is conducted at midlife.
