HPS Sentinel™ K Transformer

April 12, 2023

HPS Sentinel K  energy efficient k-factor distribution transformers are rated for 600 volts and below. K-factor transformers are specifically designed and tested for applications that use non-linear loads.

HPS energy efficient k-factor transformers are the ideal solution for harmonic distortion associated with non-linear loads.  They have been designed to tolerate the heating generated by harmonics.

Harmonics can indicate their presence in a number of ways: overheating, device malfunctions, telephone interference, equipment vibration and breakers tripping.

For applications with adverse atmospheric conditions, see HPS’s Totally Enclosed Non-Ventilated (TENV) product option.
