Hammond 3-phase general purpose ventilated transformers feature an advanced core and coil construction that provides higher efficiency, which translates to low operating costs, decreased cost of ownership, and cooling savings due to lower heat emissions. These 3-phase open core transformers offer a 480 VAC primary to 208Y/120 VAC secondary configuration in a range of kVA ratings.
HPS Sentinel G ventilated stand-up distribution transformers meet the latest energy efficiency standards as outlined by DOE and NRCan. These transformers offer significant energy savings and environmental benefits.
Higher efficiency lowers operating costs, decreases cost of ownership over the lifetime of the transformer, and reduces air conditioning costs with lower heat emissions. HPS Sentinel models are rated up to 75kVA, and the standard 10kV BIL rating (Basic Insulation Rating) provides increased reliability and protection against critical equipment failure including protection against voltage spikes and other line transients.
