IMCORP Certification Program

IMCORP Factory Grade® Certification Program

The IMCORP Factory Grade® certification program is a best in class addition to existing utility underground cable system installation training. This program is designed to further develop the knowledge level and craft skill level of contractor or direct utility installation crews. Utilities benefit from knowledge IMCORP has accumulated over the past 20 years, while ensuring cable system quality and reliability utilizing its Factory Grade® assessment technology. The Factory Grade® certification program uniquely supplements existing classroom training and classroom skills application by incorporating the Factory Grade® assessment of field installations and feedback regarding workmanship and individual skill levels.

Utilities determine the certification period and recertification requirements, typically on an annual cycle.

The IMCORP Factory Grade® certification program complements the utility and manufacturer provided training by reinforcing why adherence to installation best practices is critically important to overall distribution system reliability performance.

Benefits to Utility:

› Industry leading crew skill and craft knowledge
› Client selected quality control field assessment of: URD, critical infrastructure (hospitals, substation get aways, airports, stadiums, etc.) and other new facilities
› Improved system reliability (eliminating future outages & future O&M)
› Contractor oversight and audit of installed systems— Contractor Value Management (CVM). Utilities typically update contracts to require contractors to repair and retest any substandard workmanship found during subsequent Factory Grade® technology QC assessments

Classroom Training

Classroom and field assessments are designed to work together to reinforce accessory manufacturer and utility provided installation training, providing a roadmap for accessory and medium voltage (MV) cable system installation success in four main areas (in order of importance):
› Safety
› Reliability
› Efficiency
› Assessment technology education/defect elimination

Maintaining quality workmanship and the latest best installation practices is imperative for utilities’ contractor and direct personnel. IMCORP’s Factory Grade® certification program integrates the utilities existing training department curriculum, manufacturer handling and installation instructions and IMCORP’s classroom training to provide hands-on, practical training for the safe and reliable installation of MV cable systems

The following is an outline of the IMCORP classroom training session:

› Cable, connector & accessory design theory
› Handling and installation best practices
› What is partial discharge (PD) and how do cable systems fail?
› Review of latest industry cable system performance standards, with reinforcement of utility and manufacturer training
› Classroom sample loop construction
› Live Factory Grade® assessments of classroom installation work

Field Assessments

Upon completion of the classroom training portion of the program, IMCORP and the assist crew will go out to the field to perform assessments on installations performed by the crew prior to training. These field assessments provide a comprehensive audit of installation techniques and handling quality in the real world environment. This segment of the program is designed to assess a statistically significant sample of cable system installations performed by the crew and should be scheduled over a 5-6 day period. Both electronic data results and physical evidence is collected during this phase of the program.

Repairs & Reassessments

Once all field condition assessments are complete, the team moves back to the classroom to review the results of the field assessments and examine all physical evidence collected while in the field. Pictures of substandard components detected in the field by the IMCORP Factory Grade® assessment are used to illustrate issues of tolerance and precision.

A review of best practice tips on prevention of PD producing defects is conducted and a checklist of common issues in substandard components is presented.

Review & Certify

If any defects discovered during the field assessments still exist, the last 1-2 days of the program are set aside for a return to the field to mitigate any remaining defects and verify that all have been removed. Once all loops/radials are certified as 100% defect free, individual certifications are determined during a final review. Those performing to a level of acceptability are certified and will receive documentation to support their status for the determined certification period.
