Envirotran™ FM Approved special protection transformer

Eaton’s Cooper Power series Envirotran™ transformer is FM

Approved and suitable for indoor locations. Factory Mutual Research

Corporation’s (FMRC) approval of the Envirotran transformer line

makes it easy to comply with and verify compliance with Section

450.23, 2008 NEC, Less-Flammable Liquid-Filled Transformer

Requirements for both indoor and outdoor locations.

Envirotran FM Approved transformers offer the user the benefit

of a transformer that can be easily specified to comply with NEC,

and makes FM Safety Data Sheet compliance simpler, while also

providing maximum safety and flexibility for both indoor and outdoor

installations.

Because the “FM Approved” logo is readily visible on the

transformer and its nameplate, NEC compliance is now easily

verifiable by the inspector.

Envirotran FM Approved transformers are manufactured under

strict compliance with FMRC Standard 3990 and are filled with

FM Approved Envirotemp™FR3™ fluid, a fire-resistant dielectric

coolant.

Special application transformers

Data Center transformer

With focus rapidly shifting from simply maximizing uptime and

supporting demand to improving energy utilization, the data center

industry is continually looking for methods to increase its energy

efficiency and reliability. Utilizing cutting edge technology, Eaton’s

Cooper Power series Hardened Data Center (HDC) transformers

are the solution. Designed with special attention given to surge

protection, HDC liquid-filled transformers provide superior

performance under the harshest electrical environments. Contrary

to traditional dry-type units, HDC transformers provide unsurpassed

reliability, overloadability, operational life, efficiency, thermal loading

and installed footprint. These units have reliably served more than

100 MW of critical data center capacity for a total of more than

6,000,000 hours without any reported downtime caused by a

thermal or short-circuit coil failure.

The top priority in data center operations is uninterrupted service.

Envirotran HDC transformers from Eaton, having substantially higher

levels of insulation, are less susceptible to voltage surges. Eaton has

experienced zero failures due to switching transients. The ANSI

and

IEEE

standard impulse withstand ratings are higher for liquid-filled

transformers, making them less susceptible to insulation failure.

The Envirotran HDC transformer provides ultimate protection by

increasing the BIL rating one level higher than standard liquid-filled

transformer ratings. The cooling system of liquid-filled transformers

provides better protection from severe overloads—overloads that

can lead to significant loss of life or failure.

Data center design typically includes multiple layers of redundancy,

ensuring maximum uptime for the critical IT load. When best in

class transformer manufacturing lead times are typically weeks, not

days, an unexpected transformer failure will adversely affect the

facility’s reliability and profitability. Therefore, the ability to determine

the electrical and mechanical health of a transformer can reduce

the probability of costly, unplanned downtime. Routine diagnostic

tests, including key fluid properties and dissolved gas analysis

(DGA), can help determine the health of a liquid-filled transformer.

Although sampling is not required for safe operation, it will provide

the user with valuable information, leading to scheduled repair or

replacement, and minimizing the duration and expense of an outage.

With a dry-type transformer, there is no reliable way to measure the

health or likelihood of an impending failure.

Solar transformer

As a result of the increasing number of states that are adopting

aggressive Renewable & Alternative Energy Portfolio Standards,

the solar energy market is growing—nearly doubling year over

year. Eaton, a key innovator and supplier in this expanding market,

is proud to offer its Cooper Power series Envirotran transformers

specifically designed for Solar Photovoltaic medium-voltage

applications. Eaton is working with top solar photovoltaic developers,

integrators and inverter manufacturers to evolve the industry and

change the way we distribute power.

In accordance with this progressive stance, every Envirotran

Solar transformer is filled with non-toxic, biodegradable

Envirotemp™FR3™ dielectric fluid, made from renewable seed

oils. On top of its biodegradability, Envirotemp™FR3™ fluid

substantially extends the life of the transformer insulation, saving

valuable resources. What better way to distribute green power than

to use a green transformer. In fact, delaying conversion to Envirotran

transformers places the burden of today’s environmental issues onto

tomorrow’s generations. Eaton can help you create a customized

transformer, based on site specific characteristics including:

temperature profile, site altitude, solar profile and required system

life. Some of the benefits gained from this custom rating include:

•

Reduction in core losses

•

Improved payback on investment

•

Reduction in footprint

•

Improved fire safety

•

Reduced environmental impact

For the solar photovoltaic industry, Eaton is offering standard step

up transformers and dual secondary designs, including 4-winding,

3-winding (Low-High-Low) and 3-winding (Low-Low-High) designs.

Wind transformer

Eaton is offering custom designs for renewable energy power

generation. Eaton manufactures its Cooper Power series Generator

Step-Up (GSU) transformers for installation at the base of every wind

turbine. Additionally, grounding transformers are available for wind

power generation.

DOE efficiency

The United States Department of Energy (DOE) has mandated

efficiency values for most liquid type, medium voltage transformers.

As a result, all applicable Eaton’s Cooper Power series transformers

2500 kVA and below conform to efficiency levels as specified in the

DOE ruling “10 CFR Part 431 Energy Conservation Program”.

Underwriters Laboratories

(UL

) Listed and Labeled/

Classified

The Envirotran transformer from Eaton can be specified as UL

Listed & Labeled, and/or UL

Classified. Underwriters Laboratories

(UL

) listing is a verification of the design and construction of

the transformer to the ANSI

and IEEE

standards. UL

listing

generally is the most efficient, cost-effective solution for complying

with relevant state and local electrical codes. UL

Combination

Classification/Listing is another way in which to comply with

Section 450.23, 2008 NEC

requirements. This combines the UL

listed transformer with a UL

Classified Less-Flammable Liquid

and complies with the use restrictions found within the liquid

Classification.
