Electrical equipment maintenance plan (EMP) is the practice of conducting routine inspections, tests, and the servicing of electrical equipment so that impending troubles can be detected and reduced or eliminated.
Achieve the optimum performance of your installation and your business sustainability. With our tailored maintenance programme, adapted to your operating conditions and with on-site condition-based maintenance, we help you to improve the safety of your personnel and goods, mitigate power outages, increase your equipment's availability to maximise your productivity and energy efficiency while keeping your power infrastructure longer.
The health of your electrical distribution equipment plays a important role in the performance of your business having it run, grow and be more sustainable.
Electrical preventive maintenance and testing is one of the most important functions to be performed in order to maintain the reliability and integrity of electrical distribution systems, as well as for the protection of equipment and personnel. However, preventive maintenance of electrical systems and equipment, specifically with regard to over current protective devices is often overlooked, or is performed infrequently or inadequately. An unintentional time delay in the operation of a circuit breaker, due to a sticky operating mechanism, can cause the incident energy of an arc flash to rise, sometimes dramatically.
A well-administered maintenance plan will reduce accidents, save working personnel's lives and minimize costly breakdowns and unplanned shutdowns of production equipment.
Commissioning is the systematic process by which a piece of equipment, system, or facility is tested and conditioned to verify that it functions in accordance with the design intent and owner's operational requirements.
We deliver integrated services for Commissioning, Pre-Commissioning & Commissioning. We are a team of strong and motivated group of engineers and technicians who are passionate about helping you meet your project deadlines.
Commissioning is a mission-critical stage for an engineering project of any scale, which demands a high level of technical excellence and operational expertise. We leverage our decades of acumen and experience to offer skilled manpower for making your project a grand success. In the project pre-commissioning stage, we make detailed plans and submit it to the client for approval.
Strict adherence to the highest quality standards is the assurance of our working principle. During the commissioning phase of your project, it is important to keep strict control over the material and service quality. We also work towards ensuring that the environmental conditions will not affect the project when it is launched. Testing and Commissioning are extremely important to keep the project equipment safe and active. The experienced and professional engineers of our team are fully equipped to handle the site with safety, quality and efficiency on the system, in both pre-commissioning and commissioning stages.
We are experts in complete substation equipment testing and complete functional relay and controls testing. We have the complete suite of modern testing equipment for enabling us to do complex testing in commissioning and pre-commissioning services for our clients.
The more complex and critical the electrical system becomes and the greater the exposure to risk involved with loss of power, the more crucial it is to commission the system and verify that it will operate as designed.
In order to resolve any issue, it is necessary to duly investigate the root cause of the problem. Troubleshooting is a detailed process that includes several steps in order to effectively provide the solution.
Gather the information – for any high cost repair, it is essential to know as much details as possible so that there may be adequate information on all relevant matters. The process includes gathering all the information about the equipments and know all about its workings. As the issues are addressed including technical resources and equipment operations, It is easier to understand the malfunction.
Understand the malfunction - Understanding the malfunction means that you understand how or what the process is and what portion of the process is operating incorrectly. This includes questions like, how the process is supposed to work? What isn’t functioning as it should? What would cause the results to malfunction?
Identify which parameters need to be evaluated - Identifying which parameters need to be evaluated requires a clear understanding of the discrepancy and which signals affect the suspected component. Which input signals control the component? What is the expected output from the suspect circuit? Is there a timing delay, sequence, or set point that can be verified?
Identify the source of the problem
Correct/repair the component - Identifying the source of the problem requires the technician to isolate components and evaluate circuit parameters, to isolate the circuit by group when dealing with a complicated circuit (half-step approach), and to identify the malfunctioning component using the recorded data. Armed with data, we can determine what needs to be done with the suspect component. Many times after the first round of troubleshooting, the first three steps may need to be repeated; however, now you have additional data to work with.
Verify the repair - Correct or repair the component identified as damaged based on the recorded data. Perform the required repairs to the circuit. Completing this can range from simple adjustments to a complete component replacement.
Perform root cause analysis - Verify the repair after completion. Ensure the equipment is operating as designed. Perform another round of testing to verify the equipment is in fact running correctly and that no other discrepancies exist.
This service involves the testing and diagnosis, condition-based maintenance (CBM), predictive maintenance and commissioning services for all types of electrical installations and equipment (low-, medium- and high-voltage), including transformers, motors, generators, cables, earthed systems and rotating equipments. The testing of electrical equipment helps to determine its condition, so avoiding service failures and unnecessary preventive action.
An electrical inspection refers to the thorough checkup of the electrical connections and wiring installed in your institute and to ensure adequate functioning. Many institutes ignore the precautionary measures that have been detailed in different policies, for different electrical installations.
Furthermore an authorized person in the name of an electrical engineer is appointed who is responsible for checking and maintaining electrical connections that are in connection with the local municipal and government laws and the requirements in the area. To highlight the importance of electrical inspection we need to understand.
The aim of this service is aimed at power utilities (transmission, distribution and generation), electrical engineering companies and any company that owns industrial electrical equipment that needs to be validated during commissioning, before start-up, or once in service, whether for regular or statutory inspections.
Through a wide range of different testing techniques, we are able to provide top-rate optimisation management for any electrical installation during its useful life, including consultancy on inspection and maintenance plans and root-cause failure analysis.
