The purpose of this analysis is to monitor power availability and usage to confirm if enough AC electrical power is presently available at the building for the client’s use. Power availability and relevant notes will be included in the report, along with testing data. Sites are monitored for a minimum of 72 hours or as long as 30 days or as requested by the client. Load study reports are provided within 48 hours of monitor removal.

Required by utility company and telco for sites located at or near high-voltage utility equipment. The purpose of the analysis is to provide engineering data to determine the best course of action with regard to safety in the event of a ground fault associated with the high-voltage site. Earth resistivity testing and ground resistance calculations are included in this study. Fault data is required from the participating utility. This test is completed within 1 week of receipt of fault data from the participating utility. Site plan required.

Electrical engineering study of an investigative nature in an attempt to identify and resolve a client’s electrical problems. Includes electrical evaluation and measurements of electrical distribution system. Power analysis includes harmonics, unbalances, transients, swells, and sags. Report includes discussion of findings, data testing, and recommendations for correction.

Earth resistivity testing for grounding system design utilizing the four-point Wenner method to determine the resistivity of the earth. Typically, this test is performed before site construction. The data is used to design a grounding system that will achieve target resistance. Reports containing soil data and grounding recommendations are delivered within 24 hours.

Ground resistance verification testing is needed after installation of the grounding system. This test should be performed on every site to verify if the grounding system has met the equipment manufacturer’s and end-user’s requirements, typically 5 ohms or less. Test method is “Fall of Potential” (3-Point Method) or clamp-on method (only in special circumstances). This test should be performed before the site is connected to utility power. Once the site is constructed, ground resistance tests should be performed annually. Reports with recommendations for corrections, if necessary, are delivered within 24 hours. Grounding system drawings or description requested.
