HVS manufactures a group of Transformer Health Products™ designed to increase reliability and life of your transformer while lowering the cost of maintenance: nitrogen generators, inert air systems, dehydrating breathers, LTC oil filtration systems, PTC heaters and LTC "High Intensity" Training Classes. Although branded together for the same end result, each of these components offers its own unique functionality:
Nitrogen Generator
This product produces nitrogen from the air we breathe! HVS' nitrogen generator provides a continuous (on-demand) source of pure, dry nitrogen to protect and maintain the nitrogen blanket on sealed transformer tanks. Notable features include the following:
Produces nitrogen at 125 psi instead of the typical 2000 psi of a standard
nitrogen cylinder; lower pressure means less system leaks.
Maintains transformer tank pressure between 0.2 and 5.5 psi to protect
transformer oil from oxidation and moisture absorption.
Eliminates the need to transport and replace nitrogen bottles and the potential
risk of maintenance personnel soft tissue injuries.
Inert Air Systems
Using a standard nitrogen bottle, these positive pressure/regulated systems protect transformer oil in the main tank from oxidation and moisture absorption by keeping tank pressure at proper preset levels.
LTC Oil Filtration Systems
Our Retrofit and Retrofit-Plus systems install on most LTC models to remove carbon and metallic particles produced during normal operation, keeping oil in peak condition with minimal maintenance.
Auto-Recharging Dehydrating Breathers
Automatic recharging of desiccant maintains peak drying performance, reducing maintenance costs associated with periodic replacement/disposal of saturated silica gel.
PTC Heater
Our Positive Temperature Coefficient (PTC) heater uses a variable resistance element that automatically maintains an enclosure temperature only slightly higher than the outside ambient temperature without using a thermostat or controls thereby protecting against heat damage and condensation.
Comprehensive LTC Maintenance Training Program
Multiple manufacturer load tap changer maintenance courses teach the unwritten
knowledge and skills that can only be attained through years of hands-on experience.
