| Contact Us Services Case Studies Explorer Power 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. GE provides specialized technical services during the whole lifecycle of all high voltage transformers:
Field specialists undertake extensive investigation and condition assessment when required before repair or modernize ageing transformers. |
Installation & Relocation
GE offers the assembly and disassembly services of GE and other OEM installations including:
9T51B10 - Manufacturer General Electric / GE Part Name: 9T51B10; 1 KVA 240/480V PRI - 120/240V SEC SINGLE PHASE WALL MOUNT TRANSFORMER T-1A-53315-3S - Manufacturer General Electric / GE Part Name: T-1A-53315-3S; 112.5 KVA 480 DELTA - 208Y/120 TRANSFORMER. GE’s comprehensive suite of power transformers support a wide range of voltage levels with applications in generation, transmission and distribution. GE offers a wide variety of power transformers from medium to ultra-high voltage (1200 kV AC and ±1100 kV DC) and from small (5 MVA) to very large power ratings (2750 MVA). For Example, the GE Stackable washer and Dryer Model No.: GUD24ESSMWW with SN: RL059433C was Manufactured in August 2018 (F20-014). For Example, GE Refrigerator Model No.: TBX22PAYARBB with SN: ZR525322 was Manufactured in December 1996 (F06-013).
