SOLA Transformer
Emerson Group's
low temperature rise transformers feature a 220°C insulation system and temperature rise of only 80°C or 115°C under
full nameplate load. The result is 13-21% lower operating losses than conventional 150°C rise units.

 HPS Sentinel Series |
Hammond's line of single phase and three phase general purpose distribution transformers are rated for
600 volts and below. They are generally used for supplying appliance, lighting, motorized machine and power loads from
electrical distribution systems. They are either ventilated or totally enclosed, and are available with either aluminum or
copper windings in standard ratings from 50 VA up to 750 kVA.
Shielded distribution transformers are also available, which provide a copper electrostatic shield between
the primary and secondary windings. The shield is grounded and thus shunts most noise and transients to the ground path rather
than passing them through to the secondary. Applications for shielded transformers are similar to those above, and are ideal
for commercial or electrical installations where electronic circuitry operating at low voltage DC is present and is very
sensitive to 'noise'.

 HPS Synergy Series |
The use of electronic equipment has continued to grow in both offices and industrial plants. Either
Switching Power Supplies or rectifier circuits power these electronic devices. Examples of these devices include computers, fax
machines, copiers, printers, cash registers, UPS's and solid-state
ballasts. They all contribute to the distortion of the current waveform and the Generation Of Harmonics. General purpose
transformers, most frequently used for applications such as commercial or institutional buildings, will, by definition, supply
widely varied single phase loads as described. K Factor transformers are general purpose transformers but are designed to
tolerate the harmonic distortion associated with these loads.

 HPS Centurion Series |
Hammond is pleased to introduce a line of energy efficient, dry type, general purpose distribution
transformers to meet NEMA TP-1 specifications. In the past several years, there has been an accelerated rate of change to
introduce energy efficiency standards for transformers in North America. Many products have preceded the initiatives for
transformers in an overall effort to optimize manufactured goods for environmental concerns. Governments are encouraging users
to consider energy efficient products like dry type transformers, in an effort to help reduce carbon dioxide emissions. In
addition to the benefits to the environment, energy efficient transformers also can realize substantial savings in operating
costs thereby having a direct impact on the initial investment evaluated over a period of time.

 Drive Isolation |
With today's technological advances in solid-state power control devices, the use of AC and DC
VFD has proliferated in many
industrial markets. General purpose distribution transformers are not adequate for this type of application.
Hammond Drive Isolation Transformers are designed to meet the rugged
demands of both AC and DC variable speed drives and also to provide the required voltage change.
The separate primary and secondary windings provide electrical isolation between the incoming line and the
SCR load. The windings are designed to withstand overcurrent of 150% of the rated load for 60 seconds or 200% of the rated load
for 30 seconds. A duty cycle of one start for every two hours is permitted. Drive Isolation Transformers are sized to match
standard Motor Horsepower & Voltage Ratings. Standard sizes range from 5 to 600 HP in six standard voltages in both aluminum
and copper. Nonstandard sizes and voltages are available upon request.
|
 Autotransformers |
Hammond three phase autotransformers are available for applications where small voltage corrections are
necessary in a distribution system. They are frequently used as an economical alternative to three phase general purpose
distribution transformers to adjust the supply voltage to match specific load requirements when load isolation from the supply
line is not required. Autotransformers can be used as either a step-up or step-down transformer. Available with either aluminum
or copper windings in ratings from 3kVA to 500kVA.
|
 Custom Transformers |
Hammond custom distribution transformers are designed and constructed to meet or exceed the requirements
of our standard distribution transformer general applications. These transformers are provided either ventilated or totally
enclosed. To meet special applications and requirements, custom/specialty designs are available to meet your specific application
needs.
