The Station Service Transformers have the characteristics of both the voltage transformer as well as convenient power capability. This type of transformer provides full insulation for up to 362 kV and with a power performance of up to 333 kVA. Such combination has resulted to the high voltage transmission line for an economical, peseta mounted and conveniently installed transformer device. The transformer takes power directly from the high voltage primary towards the low voltage which capable of supplying a 125/250 power in order to drive lighting loads, instrumentation, as well as motor loads. The typical secondary ratings that are available for these types of transformers are similar to the Drive Duty Transformers, which is from 115 VAC to 600 VAC.

Set-up

The Station Service Transformers are often being mounted towards a pedestal wherein the primary is tied directly towards the transmission line. The secondary output wiring is then connected to the station power panel while the secondary power is obtained directly from the transmission line which assures reliability. Here are two main functions of the Station ...
... Service Transformers:

• Used for measuring and protecting as well as in providing auxiliary power.

• Eliminates reliance on the outside power sources.

Remote Cell Tower Site Application

It is usually required that site cell towers on remote locations will have repeating phone transmissions. A tap might be taken from the transmission line towards the station service voltage transformer. This provides a substantial amount of savings as compared to installing a dedication distribution feeder or perhaps a diesel generator. Here are more advantages of using service stations, like the Drive Duty Transformers.

• user advantage of power purchases and at transmission level

• avoid costs associated to site permits by making use of existing towers

• avoids any possible outages

Reliable Power

The Station Service Transformers also helps to eliminate reliance on distribution lines that are often vulnerable on power outage. Also, it minimizes reliance on power transformer tertiary for controlling power. The power that is supplied from within the Substation Service also helps to improve reliability. The SSVT also helps to reserve power transformer tertiary windings that control harmonics. It also comes with dual function enclosed on one transformer unit and functions as a power source.

Rural Electrification Application

On most developing countries, the transmissions are often in place yet the distribution system is what’s lacking. The Drive Duty Transformers along with the SSVT can be used as an economical substation that provides power distribution service to a compact area like in a rural community or in a village. The low voltage output as a direct supply for loads that are in close proximity. The substation that is provided with step up transformer that is ideal for 15 KV, 25 KV and 35 KV power distributions. It is also capable of up to 333 KVA single phases or as much as 1,000 KVA three phases available.

The Station Service Transformers certainly functions efficiently especially when it comes to supplying both control power as well as tap voltage indication that helps to monitor SCADA circuits in order to result to automatic switch applications.
