Mining Industry


There is a serious problem surrounding downtime, degradation and disruption of electrical equipment in mining applications. PhaseFree Inc. provides electrical and electronic equipment that solves the problems of equipment malfunction. Their products include Transient Voltage Surge Suppression (TVSS) and Surge Protection Device (SPD).


Electrical and electronic equipment play an important role in the mining industry. Unmanaged power quality results in equipment failure and process disruption while reduced equipment life will prevent a mine from running at full capacity.

A transient-free electrical environment does not exist. Loads turning on and off, generator systems and even electronic and electrical loads can cause power disturbances in mines.


A Transient Voltage Surge Suppressor (TVSS) protects vital pieces of equipment and minimizes downtime in a mine's electronic equipment.

TVSS provides the highest return on investment of any piece of power quality equipment and should be the first step in managing power quality. TVSS is easy to install and requires no regular maintenance.

The correct installation of a high quality TVSS in the correct location of an electrical system provides an excellent return on investment. The US Navy collected return on investment (R.O.I) data that showed a significant R.O.I .The benefits of TVSS installation include:

     •    Increased equipment life
     •    Reduced maintenance man hours
     •    Reduced repair and parts costs
     •    Improved operation and process reliability
     •    Decreased computer lock ups
     •    Reduced downtime


SPD protects electronic equipment from damaging transients. The PhaseFree SPD is suitable for high, medium and low exposure levels, and sensitive, emission-critical load applications including:

     •    Switchboards / main panels
     •    Distribution panels
     •    Branch panels
     •    Critical load centers
     •    Dedicated load protection
     •    VFD (Variable Frequency Drives)
     •    Motor protection
     •    Motor controllers
     •    PLC’s
     •    Soft Starters

Since 2000, PhaseFree’s Team has been producing SPDs that provide field-proven power quality solutions worldwide. PhaseFree has a rugged device, ideal for the harsh conditions of a mine. It is easy to install adjacent to or even inside electrical equipment. Based on extensive proven field performance, PhaseFree offers a 10 year replacement warranty.

Steve Salka one of PhaseFree’s owners was the senior electronics officer for the US Navy and had all TVSS tests conducted to insure that the US Navy technical requirements for TVSS provided a return on investment and manpower reduction that reflected suitable maintenance cost avoidance.
