Transformer Solutions
for Arc Flash Risks
Prolec GE has developed options for reducing arc flash
risks to personnel responsible for installation, operation
and maintenance routines during transformer operation.
Typically, in renewable applications, transformers are very
close to the generation point, which justifies precautionary
measures against an arc flash event. Our solutions focus
on the safety of personnel by offering several packages
for added protection.
Tamper-proof
pad lockable
enclosures for

Typical Operation and Maintenance activities
performed on a transformer for renewable
applications:
• Switching transformers in and out of the collection circuit
• Routinely taking oil samples for dissolved gas analysis
testing
• Monitoring tank pressure and adding gas as needed
• Performing infrared temperature scans of the HV and
LV connections

Optional features & accessories
Prolec GE offers a complete line of liquid-filled distribution
transformers that meet current applicable ANSI™ / IEEE™
standards.
In addition to the already existing Substation Transformers
product line Prolec GE now offers its brand new
transformers, with high voltages from 34.5 kv to 69 kV
and ranging from 5 MVA to 12 MVA (ONAN). These type
of transformers are used in a wide range of utility, and
industrial applications. High-grade materials, combined
with state of the art technology in our design and
manufacturing systems, are key elements of a transformer
that will deliver years of high reliability service.
Prolec GE Substation Transformers meet all of your
industrial applications for electric distribution.
