Testing and Commissioning In Electrical Construction Works At the completion of the electrical installation works, the entire installation shall be subject to the test before final placing in service under the full responsibility of the contractor Start-up Testing Electrical commissioning is essential to the start up of any electrical system for the first time, regardless of size or industry. Once equipment is installed, Electrical Testing Solutions will perform visual, mechanical, and electrical tests to help ensure trouble-free energizing of the equipment
Commissioning on-site electrical systems Commissioning is the systematic process by which a piece of equipment, system, or facility is tested to verify that it functions in accordance with the design intent and owner's operational requirements. By Kenneth Kutsmeda, PE, KlingStubbins, Philadelphia September 1, 200 Testing & Commissioning Testing & commissioning is done once all civil & MEP system installation is completed, inspected and approved. Before starting the T&C activities a comprehensive testing & commissioning plan is prepared and approval is taken from client/consultant Electrical systems commissioning (referred to as acceptance testing) on new projects is critical to ensure that a system is installed correctly and that it will remain in service for its projected life cycle. 1-2
In the ANSI/International Electrical Testing Association — Standard for Electrical Commissioning Specifications for Electrical Power Equipment and Systems (NETA ECS-2015), electrical commissioning is defined as the systematic process of verifying, documenting, and placing into service newly installed or retrofitted electrical power equipment and systems Today I will talk about Testing & Commissioning (T & C) since it is the trend right now and will try my best to make it simple for easy understanding by engineers. Here's the deal, there are 9 key elements of successful commissioning, briefly, they are as follow; 1- Planning Risk assessment (Safety); the first Pre-Requisites for switchgear testing and commissioning. Obtain the permit to work PTW for starting the electrical testing and commissioning T&C activity. PTW should be signed by all parties with valid dates and times related to the specific activity and equipment. Physical checking or pre commissioning procedur Upon completion of static testing, dynamic testing can be undertaken, this is ' commissioning '. Commissioning is carried out to prove that the systems operate and perform to the design intent and specification
Testing and Commissioning Requirements for Switchgear Before starting the switchgear testing an approved testing & commissioning engineer should be appointed in order to thoroughly review all the applicable drawings and specification, and to become totally familiar with all systems and the design intent Resource: Procedures for Testing and Commissioning of Electrical Equipment by Schneider Electric.

Electrical systems providing energy to all the systems in building including HVAC, Lighting, Security, Safety, Communication and Monitoring Systems. Commissioning of Electrical Power Systems is important because most electrical failures often occurs as catastrophic events and are not detected until a fault or failure occurs 4. Electrical Commissioning Checklist. This electrical commissioning checklist is used for the commissioning of low voltage installations in a building. Use this checklist to verify the compliance of the switchboard, main switch and circuit breaker, distribution board, and final circuits with client specifications
Commissioning Procedure Of Power Transformer In Transformer testing it can be classified into power and distribution transformers. It Rating plate show nominal voltage, current of primary and secondary voltage at various of the tap changer, connection symbols ( vector group), % impedance weight of oil etc The most important pre-commissioning tests and in-service checks of protection system can be summarized as follows: Analysis of the wiring diagrams to confirm the polarity of connections, positive and negative-sequence rotation, etc Testing and commissioning are to be carried out on installations to ensure that they are safe and meet the design requirements. This can happen in many aspects of a business or building, and it requires extensions checks of the electromechanical relays to ensure they are performing appropriately and there is a power system protection The purpose of electric systems start-up, commissioning and testing is to increase the stability, integrity and reliability of electrical power systems after installation by identifying problems and providing a set of baseline values for comparison with subsequent routine tests
Objective.

The inspection and testing performed on an electrical power system and its components before the initial energization is key to lifecycle reliability. Proper commissioning and start-up testing also provide a valuable baseline or benchmark that can be used to shape the equipment's future maintenance program Testing and commissioning can include acceptance and compliance testing as well as troubleshooting and predictive and preventative maintenance plans. For the EC, testing and commissioning protects the integrity of the contracting relationship and the interests of the clients and their buildings Acceptance testing and commissioning are performed to ensure the electrical apparatus meets industry and manufacturer standards and prove all protection controls and SCADA systems are operating as per engineered design. New electrical equipment requires acceptance testing and commissioning after being installed regardless of the size or industry 7 Cabling Commissioning and Periodic Testing 125 7.1 Review of Codes for Testing 125 7.2 Drum Length Checks 127 7.3 Post Installation Checking 128 7.4 Pre-commissioning and Periodic Tests 129 7.5 Tests as Tools for Condition Monitoring and Early Failure Alarm 129 7.6 HV Tests Using DC and Very Low Frequency AC 13 Testing is the act of conducting a test or trial.
