|
At High Voltage Supply, we understand that todays utilities are driven to improve asset management more now than ever. This has lead to higher loads over longer periods of time with less maintenance on an aging base of substation electrical equipment. The result: the need to repair and upgrade existing equipment with the latest available technology for increasing load capacity, improve reliability, eliminate "typical" failure modes and/or extend maintenance intervals.

FEA Analysis on TC546 Diverter Casting |
Our extensive experience in reverse-engineering and our ability to redesign and upgrade has made HVS an industry leading provider of enhanced design replacement components.
We utilize the latest technology and design tools when developing a design enhancement. Our engineering team uses 3-D modeling to test-fit mating parts and determine acceptable tolerances as well as perform Finite Element Analysis (FEA) to evaluate mechanical stresses when redesigning an original part.
HVS has pioneered many design enhancements such as:
|
Ferranti Packard
TC25RT32 Reversing Switch with ELR® Inlay
|
 |
Example of Contact with Coking |
ELR® (Extra Low Resistance) Series contact design for LTCs that eliminates heating and carbon build-up (coking).
Self aligning selector contacts and upgraded diverter castings for the FPE TC 525 and TC 546 load tap changers
Spring redesign using stainless steel capable of maintaining spring rate at higher operating temperatures
 |
Enhanced Life Interrupter Materials |
Upgraded oil circuit breaker interrupter materials with longer arc erosion life
Materials upgrade from moisture absorbing phenolic to moisture resistant fiberglass reinforced epoxy
Thorough in-house LTC overhauls/upgrades on many makes and models including GE LRT200, Seimens TLH, TLF, TLG, & TLS series
