Customer Success Stories

Many customers have recognized the exceptional protection and communications capabilities in upgrading their equipment. 

  • G&W Electric worked with a utility in the Northeast region to help them switch while using a similar interface in the controls they were using before. The work included customization, extra hardware, and development work to meet customer-specific requirements. 
  • Comparably, we did a similar emulation for another utility in the Midwest, but without the extra hardware, and included automation logic for a non-communicating FLISR scheme with recloser, sectionalizing, and/or tie automation profiles.
  • A few coops in the Midwest have reached out to us to do a more basic conversion. To meet their needs, we took the existing Form 6 protection and reclosing settings and migrated them into the SEL-651R 32-pin template. 

We have focused on helping electric cooperatives and municipalities overcome obstacles related to service reliability and outdated equipment limitations. Customers have chosen Viper-ST for the field-proven solutions and the close work with their specific requirements.

Testing, Support, and Training

G&W Electric provides Factory Acceptance Testing, Site Acceptance Testing, Commissioning Support, and Training for all our solutions, including recloser and recloser controls.

Aside from providing full turn-key automation solutions, we have expertise in converting settings and user interfaces from one control vendor to another with the goal to make transitions easier for both engineers and operators.  G&W Electric is a strong partner of SEL and GE and complements their offering for any upcoming transition from legacy controls to SEL or GE products paired with G&W Electric products.

When it comes to switching from legacy Cooper controls to SEL or GE controls, G&W Electric can provide the following options for you to consider incorporating, ranging from simple to complex:

  1. Form 6 settings conversion/migration.  Use G&W Electric’s SEL-651R2 or GE 850R/R650 template and migrate Form 6 settings. Includes protection and reclosing only.
  2. Form 6 loop scheme emulation. A higher degree of customization. Includes loop scheme recloser, sectionalizing, and/or tie automation.
  3. Form 6 loop scheme emulation in one program. The highest degree of customization. Includes extra hardware and customized development work to meet customer-specific requirements.

G&W Electric can help bridge the gap between your current installations and the technologies you are evaluating for the future by providing support and training.
