How does an aging plant replace obsolete
equipment without massive capital
expenditures? By calling on HVM to
upgrade their assets with rebuilt and
retrofitted equipment—at a savings of up to
2/3 the cost of new replacements.
Our dedicated shop and expert technicians
perform upgrades on:
480v Circuit Breakers
– Upgraded with new solid state trip units,
electronic communication technology,
adjustable settings, enhanced protection,
power quality monitoring, energy management
capabilities and more.
2400v to 15,000v Circuit Breakers
– Upgrades to vacuum and SF technology.
These upgrades improve reliability and
decrease maintenance intervals. Other
benefits include improving the interrupting,
momentary and continuous current rating.
High Pressure Switches, Starters/Contactors,
Motor Control Centers
– Completely rebuilt including replating,
polishing, hardware replacement, painting,
replacing into existing cell, testing and
calibration.
Relays
– Upgrades from old electro-mechanical
relaying systems to new solid state packages
from Schweitzer, GE, Basler, and more. These
upgrades provide better system protection
flexibility, more independent function
availability, small packaging for panel or
rack mount, LCD displays with real-time
metering and system monitoring,
communication ports for metering, alarms and
fault data monitoring from remote locations,
and reduced maintenance and calibration
costs.
Direct Replacement
Breakers
- Circuit breaker technologies allow large
electrical users to exchange older, often
obsolete equipment for upgraded
replacements, without disrupting existing
switchgear. Most replacement breakers are
designed to fit into the existing switchgear
cell with little to no modification and will
interface with the existing switchgear
structure and maintain safety interlocks
inherent in the original design.
Benefits of replacement circuit breakers
typically include:
l
Enhanced electrical system reliability
l
Less cost and downtime compared to new
equipment installation
l
Reduced maintenance and operating costs
l
No need for obsolete or hard-to-find spare
parts—available for most manufacturers’ LV
l
ANSI
switchgear
l
Various digital trip devices for short
circuit and overload protection
l
Extended range of short circuit and
continuous current capabilities
l
Increased safety by adding ground fault
protection
l
All applicable ANSI standards met
l
Through-door racking and trip unit display
l
Increased safety by replacing with arc flash
limiting breakers
