  1. Safety Protocols: List out all safety protocols and get the necessary protective equipment.

Before moving a pad-mounted transformer, it’s crucial to follow strict safety protocols to prevent accidents and damage. One common safety measure is conducting a “lockout-tagout” procedure, which involves locking the transformer’s control panels and placing a warning tag. This process ensures that no one can accidentally energize the system during the movement, safeguarding both workers and the equipment.

The Process of Moving a Pad Mounted Transformer

Initial Assessment

The first step in moving a pad-mounted transformer is carrying out an initial assessment to identify key factors such as size, weight, and the complexity of disconnection. This phase is crucial because it helps you gauge the manpower, machinery, and time frame required for a smooth relocation.

🔗 How to Size a Pad Mounted Transformer

Isolation and Disconnection

Isolation is paramount for ensuring safety during the process. The transformer must be disconnected from the electrical grid to prevent any accidental flow of electricity that could endanger the workers or damage the equipment. Particular attention should be given to the technical parameters like voltage ratings, winding configurations, and tap changer settings before disconnection.

🔗 Seven Technical Parameters of Pad Mounted Transformer

Physical Movement

Once the transformer is safely disconnected and isolated, the next step involves the actual physical movement. This process usually requires specialized lifting equipment due to the weight of pad-mounted transformers. In Texas, for example, experts may employ hydraulic jacks and specialized trolleys designed to maneuver heavy machinery.

  1. Lifting: Hydraulic jacks are generally employed to lift the transformer off its base.
  2. Transporting: After lifting, the transformer is placed on a trolley or truck for transportation. Given the high temperatures in Texas, particular care is needed to ensure the equipment doesn’t overheat during this phase.
  3. Repositioning: Upon reaching the new location, the transformer is carefully lowered into position. Alignment is critical here to ensure efficient operation post-installation.

🔗 What Are Pad Mounted Transformers?

Moving a pad-mounted transformer is a highly specialized job that demands meticulous planning and strict adherence to safety protocols. In states like Texas, where the environment can offer unique challenges, relying on expertise and high-quality equipment is crucial for a successful operation.

Post-Movement Steps

Reconnection and Commissioning

After the pad-mounted transformer has been moved to its new location, the next critical phase is reconnecting it to the electrical grid. This involves wiring it back based on the technical parameters you initially noted. It’s imperative to cross-check all connections to avoid any electrical hazards. In Texas, where weather conditions can be harsh, ensuring a weatherproof connection is also vital.

Safety Checks

Once reconnected, an extensive set of safety checks must be performed. This includes thermal imaging to look for ‘hot spots’ that could indicate a poor connection, insulation resistance tests, and functionality tests of all in-built safety features like the circuit breaker.

🔗 How to Maintain a Pad Mounted Transformer

Certainly! Let’s delve into the specific steps and tests involved in the Safety Checks phase for moving a pad-mounted transformer. This process is crucial for ensuring both operational efficacy and long-term safety.

Visual Inspection

Step 1: The very first thing you want to do is conduct a comprehensive visual inspection of the transformer and its components. Look for any visible damage like dents or cracks, and make sure that all the protective covers and caps are in place.

Example: In a case in Texas, a quick visual inspection revealed a loose bolt that had been missed during the reassembly phase. Ignoring such a seemingly trivial issue could have led to serious operational issues down the line.

Electrical Testing

Step 2: Before energizing the transformer, various electrical tests need to be performed, such as insulation resistance testing and winding resistance tests.

Example: Using a Megger, you’ll apply a direct voltage to the transformer’s windings to measure insulation resistance. The results should meet or exceed the manufacturer’s specifications, often detailed in documents conforming to international transformer standards like IEEE or IEC.

Thermal Imaging

Step 3: This involves using thermal imaging cameras to detect ‘hot spots’ in the electrical system. Hot spots can indicate a faulty or loose connection that may cause overheating or even fire if left unattended.

Example: In a facility in Texas, thermal imaging revealed a hot spot at one of the connections, prompting immediate corrective action.

Functional Tests

Step 4: Run functional tests on all in-built safety mechanisms like circuit breakers and surge protectors to ensure they are working correctly.

Example: In the Texas context, due to frequent storms, surge protectors are essential. A simple test can be performed by simulating a surge and observing whether the protector cuts off the supply, as it should.

Final Power-up and Monitoring

Step 5: Once all the checks are complete and everything is in order, power up the transformer and closely monitor its performance for any irregularities.

Example: Keep an eye on the temperature and power output for the first few hours. Any deviation from the norm could indicate an issue that may have been missed in the earlier checks.

🔗 How to Maintain a Pad Mounted Transformer

With these comprehensive safety checks, you’re ensuring that your pad-mounted transformer not only resumes operation smoothly but also operates safely in the long run. By taking these precautions, particularly in complex environments like Texas, you’re investing in peace of mind and long-term reliability.


Moving a pad-mounted transformer is not an endeavor to be taken lightly. It involves multiple complex steps—each requiring specialized knowledge and equipment. From the initial assessment phase through to reconnection and safety checks, each step must be executed with the highest degree of precision and care.

Here in Texas, where environmental conditions can add an extra layer of complexity, the role of experts becomes even more critical. And this is where Daelim-Belefic shines, with years of experience and a diverse range of high-quality transformers suited for all sorts of specialized requirements.
