Does HPS build secondary unit substation transformers?
Secondary Unit Substation Transformers feed low voltage switchgear or switchboards. They typically range from 150 kVA to 2,500 kVA three-phase. The Primary voltage ranges from 2400 VAC to 34,500 VAC and the secondary from 600VAC to 480 VAC. Taps are typically manually changed while the unit is de-energized. The primary connections are typically delta connected while the secondaries are usually wye connected.
The units are typically installed inside a building and are either dry (VPI) or cast coil because of safety and installation concerns. These units are often connected directly close coupled to the switchgear. HPS can provide both VPI and Cast Coil Secondary Unit Substation Transformers.
