1 PURPOSE

1.1 The new electrical equipment and components as defined in Section 3.0 of this report have been inspected and tested to help assure that each component meets manufacturer's and industry standards.

1.2 Evaluating the performance of new equipment prior to energization is considered the most important test the equipment ever receives. These tests often reveal hidden defects, design or installation errors or in-transit damage, which can lead to serious system malfunction and down time.

1.3 This initial testing provides a database for future maintenance system analysis and equipment modification. These test results, when compared with the results from future periodic maintenance tests, can be indicative of life expectancy and thus provide a continuing monitor of reliability throughout the life of the equipment.

2 SUMMARY

This project was initiated by Mr. Roger Pombrol with Emerald Standard Services Inc. All testing was performed by Electrical Reliability Services Field Engineer Richard Carrera, Travis Keck between Tuesday, July 10, 2012 and Saturday, August 25, 2012.

Please refer to Section 5 “Results and Recommendations” for complete details of the testing.

3 EQUIPMENT TESTED AND INSPECTED

1. Ground wells at corners of building, switchgear A and B.

2. Crawl space ground loop-to ground plate connections.

3. Crawl space ground loop-to outside counterpoise loop connections.

4. Sub-floor ground plate and inter-loop connections as per drawings

E201-E204.

4 PROCEDURES

Grounding Systems

Visual and Mechanical Inspection

Reference No.3149368 Page 2

Inspected ground system connections for completeness and proper termination in accordance with design drawings, if available.

Electrical Tests

Performed "fall-of-potential" method test on the main grounding electrode per IEEE Standard No. 81. If suitable locations for test rods were not available, a low resistance dead earth or reference ground was utilized.

Performed "two-point" method test per IEEE Standard No. 81, to determine the ground resistance between the main grounding system and all major electrical equipment frames, system neutral and/or derived neutral points.

5 RESULTS AND RECOMMENDATIONS

5.1 The equipment listed in Section 3 was found to be satisfactory, as indicated by the attached field data sheets.
