Testing and commissioning (Stage 6)

testing and commissioning procedures

Having knowledge of key design decisions helped the commissioning agent to develop the validation testing procedures. The CxP should be contracted directly by the Owner. The commissioning process main goal is to improve a project from the design phase through post construction and occupancy. Green building rating system compliance and other project requirements define the goals for energy and water consuming equipment; utility incentive programs are equipment specific and must be clearly identified, depending on what has been funded; pharmaceutical facilities must comply with the U. Surge arrestors if present is to be disconnected.

testing and commissioning procedures

No matter your energization needs, maintaining efficient, long-term operations of your power delivery equipment is essential to success. If the CxP's firm has other project responsibilities, or is not under direct contract to the Owner, a conflict of interest may exist. Compliance We work cooperatively with regulatory agencies, and with clients, to maintain a safe and compliant work environment. The first step tests each piece of equipment separately to ensure that it functions correctly before testing the equipment as an electrical system. The health and safety of our employees, the projects we undertake and the communities in which we live, are paramount in all that we do.

Commissioning of Electrical Equipment

This is especially true with highly complex systems and automated controls. For correct connection no voltage difference shall be observed during phasing. The following steps are followed. During the construction phase, all parties reviewed equipment submittals, and all critical electrical equipment was factory witness tested. A CxA has to be able to give open constructive criticism while also being able to listen attentively. Once on-site, any equipment defects or problems can cause delays in the construction schedule. The month after the facility was fully commissioned, the owner started a worldwide migration to the new facility.

Owner's Role and Responsibilities in the Commissioning Process

The insulation resistance shall also be measured between all conductors connected to one phase conductor of the supply and all the conductors connected to the middle wire to the neutral or to the other phase conductors to the supply. Contractor shall coordinate with the Client and the Supervising Engineer to get electricity from the local supply authority before starting of testing and commissioning. This page is about incorporating a project's performance requirements into a plan that defines the commissioning scope, process, responsibilities, budget, and documentation requirements. A review of shop drawings submittals for all major electrical equipment provides the design team and the commissioning agent with the opportunity to confirm that the manufacturers are providing the equipment as specified and that the systems meet the design intent. It is the responsibility of the commissioning agent to confirm that the factory testing procedures are adequate or develop additional testing procedures to ensure that the equipment operates as required to meet the design intent. Electrical Testing of Non-linked Single Pole Switches In a two wire installation a test shall be made to verify that all non linked single pole switches have been fitted in the same conductor throughout, and such conductor shall be labeled or marked for connection, throughout, and such conductor shall be labeled or marked for connection to an outer or phase conductor or non earthed conductor a test shall be made three or four wire installation a test shall be made to verify that every non linked single pole switch is fitted in a conductor to one of the outer or phase conductor of the supply.

What is Commissioning

During this test, various partial systems failures can be initiated to stress the system and validate backup system performance. Typically contracted directly to the Owner. Energization Once our team determines that individual pieces of equipment are operating properly, our testing engineers energize the entire system to verify it is operating as intended and meeting requirements. The goal of 'Whole Building' Design is to create a successful high-performance building by applying an integrated design and team approach to the project during the planning and programming phases. The goal of the Retro-Commissioning Process is to discover these deficiencies and propose or provide solutions to them. Many crucial decisions made during the design phase impacted the operation of the facility and commissioning. Additional information on Building Commissioning can be found in.

What may be the reason? Details of systems tests and procedures, assembly specific checklists, and testing and documentation responsibilities are incorporated in construction phase commissioning plans. Commissioning of an existing building that has never undergone commissioning is often referred to as retrocommissioning. At normal load condition there should be no differential current and voltage. Assurance of performance and operation by the CxA's commissioning verification of the facility typically provides a better operating, performing, and comfortable environment for the owner and occupants. A commissioning schedule is developed as a section of or appendix to a commissioning plan and is updated throughout the project.

Timely delivery of these documents to the CxA is important to facilitate the CxA ample time to review, develop test, obtain reviews, and implement changes prior to scheduling of any testing. Resistance we can say short or open in turns 4. We mobilize teams to all parts of the U. At the completion of the works, the entire installation shall be subject to the test before final placing in service under the full responsibility of the contractor. This is where the entire facility as a whole is tested.

During this phase the owner also determined that all critical electrical systems would be factory tested and then validated through on-site testing. Factory testing provides the design team and commissioning agent with an opportunity to inspect and test the functional operation of the equipment before it arrives on-site. Smaller facilities may not have any discrete systems. Preventive and Predictive Maintenance We also provide consultation for development of electrical system maintenance programs that help prevent unplanned outages and maximize service life. Building controls also have the ability to monitor and control systems to improve performance, conserve energy, conserve water, and control lighting. Acceptance Testing Our test personnel inspect and provide acceptance testing on each piece of equipment to verify it meets specification to energize, will operate as designed, and performs as an integral part of the system. The commissioning scope will be dictated by the type and size of the facility.
