Testing and Commissioning Service
TESTLEADS ELECTRICAL SERVICES is testing and commissioning services provide the expertise to complete your project safely, per your plans and specifications, on time, and within budget. Proven testing and commissioning procedures is essential to the long-term reliability of an electrical system. Improper installation and commissioning can cause equipment failures. With TESTLEADS testing and commissioning services, you can be assured that your equipment has been tested and commissioned properly.
More than half of early equipment failures can be traced to design, installation, or testing deficiencies. Many avoidable outages are due to improper testing procedures, coordination and calibration of protective devices as well as wiring errors, design errors, etc.. In other cases, the failures don't occur until months after the equipment has gone into operation and the warranties have expired.
When improper testing and testing procedures are applied, the results can be devastating. Your electrical system could experience a catastrophic failure due to relatively small installation and testing errors. TESTLEADS’s Commissioning & Testing Services can verify that the equipment has been properly installed and its function complies with the purchase specifications and design.
Design Review
TEST LEADS technical staff can conduct a design review of your electrical distribution system to identify areas to reduce potential hazards. Several areas are evaluated including fault levels, exposure times, remote operations, remote racking, and system grounding. Employing special devices and altering current design can significantly reduce fault levels, arcing time, arc incident energy, and arc blast force. Conducting a design review is the most effective way to uncover potential hazards so these types of solutions can be employed.
Single Line Diagrams
Requirements mandate accurate, up-to-date single-line diagrams. These documents are essential for documenting, troubleshooting, and communicating information about your power systems. To meet these requirements, TEST LEADS can conduct a comprehensive site survey that is essential to develop or to update existing single-line diagrams or complete electrical system drawings.
Short Circuit Co-ordination and Studies
The Petroleum and Chemical Industry recommend that Arc Flash calculations be completed in conjunction with short circuit calculations and protective device coordination to achieve the most accurate Arc Flash Hazard results. Short circuit and coordination studies verify protective devices and arc hazard ratings, calculate momentary interrupting and relay currents, establish settings for all types of protective devices, and coordinate your entire power distribution system to minimize downtime. TESTLEADS specializes in conducting these studies that provide vital information you need to ensure compliance with OSHA requirements.
Electrical System Acceptance Testing and Services
Acceptance testing and testing services provide customers with the assurance that their equipment complies with the qualifications and establishes a base line for future reference.
