Electrical Maintenance Works

One of the core strengths of I2R Consulting & Engineering Services Pte Ltd (I2R) is the ability to provide comprehensive maintenance and testing for all types of HT and LV electrical apparatus. The group of specialized staff, comprising HT & LT Testing LEWs, testers, and technical officers, are equipped with the latest testing equipment and tools that allow I2R to fulfill the needs of our clients in compliance with local and IEC standards, as well as Energy Market Authority (EMA) licensing requirements. Comprehensive reports covering all test results, findings, and recommendations will be provided for each maintenance service.

Through the use of IT technologies, I2R is able to trend, record, and monitor all maintenance works done for each of our clients. This provides convenience to our clients, as they will not need to worry about missing any maintenance reports or monitoring the next maintenance cycle for their electrical apparatus.

Power shutdown maintenance is a major event for any type of building. A power shutdown event involves good planning, establishing a power shutdown sequence, and identifying affected areas. With many years of I2R’s experience in maintaining electrical apparatus, I2R is able to establish a comprehensive maintenance sequence to guide all our clients. This includes the establishment of condition monitoring works, power interruption plans, manpower allocation plans, and a sequence of electrical switching operations, including time management of the maintenance works. This provides clients with full information on all required works in advance for necessary planning and arrangements.

I2R provides a wide range of maintenance services. Below is the list of maintenance work provided by I2R:

Condition Monitoring

  • HT Switchgear & Transformers Partial Discharge Test (TEV, Ultra-sound & HFCT)
  • Oil-filled Transformer Dissolved Gas Analysis Test and Oil Quality Test
  • Infra-red Thermography Scanning
  • SF6 Gas Test and Analysis
  • Pre-shutdown inspection (with report) to check for any signs of abnormality (such as transformer oil leaks, low oil levels, low pressure, temperature, and for HT Gas Insulated Switchgear, we will check SF6 gas levels). The inspection also includes checks for any faulty protection relays, power meters, etc.

Condition Monitoring and Pre-shutdown maintenance are crucial tasks as they provide early detection of abnormalities, allowing for effective rectification during the power shutdown maintenance. This prevents numerous unwanted power shutdowns, which can be very disruptive to business operations.

  • Servicing and Testing HT Switchgear (Gas Insulated and Air Insulated types)
  • Servicing and Testing of Transformers (Cast Resin Dry Type and Oil-filled Type)
  • Servicing and Testing of Low Voltage Switchboards
