Electrical Equipment Removal Inside an Active Powerhouse: A Northwest Utility Project

Project Overview

Electrical equipment removal inside a powerhouse requires more than labor and hauling. It takes planning, field experience, equipment knowledge, and careful coordination around site conditions that can affect safety, access, and transportation.

For this project, Transformer Technologies worked directly with an Northwest Utility to dismantle and remove electrical equipment from a powerhouse and nearby warehouse building. The scope included 15 PTs/CTs located on the 6th floor of the powerhouse, along with 6 additional units located in the warehouse building. Because of the equipment location, floor access, and movement limitations, each unit had to be cut into smaller sections before it could be safely moved across the facility.

The work required controlled dismantling, load management, material staging, and

transportation to Transformer Technologies’ Salem facility for further processing.

The Challenge: Removing Heavy Electrical Equipment from an Upper Floor

Utilities and electrical contractors often face removal projects where equipment is located in tight, elevated, or access-limited areas. In this case, the equipment was positioned on the 6th floor of a powerhouse, which created several practical challenges:

• Equipment had to be dismantled into manageable sections.

• Materials needed to be moved using pallet jacks or hand carts.

• Floor load capacity had to be verified during the removal process.

• Dismantled sections had to be transported by service elevator.

• Materials needed to be staged outside the powerhouse before loading and transport.

This type of work requires more than simply cutting and moving equipment. Each step has to account for weight, floor rating, access routes, handling equipment, and containment requirements.

Step-by-step dismantling of PTs / CTs

Controlled Dismantling and Material Handling

Transformer Technologies’ crew used a gantry crane and chain hoist to support the dismantling process. The tops of the units were cut to expose the cores, allowing the crew to access and remove internal components. For taller units, a Sumner lift was used to remove lids safely and efficiently.

As materials were removed, different types of equipment components were weighed with a portable scale. This helped the crew confirm that the movement of dismantled sections remained within the provided floor load rating. That step was especially important because the work took place on an upper floor, where uncontrolled movement of heavy material could create unnecessary risk.

Moving Equipment Through a Restricted Access Path

Because the equipment could not be removed as whole units, Transformer Technologies’ crew reduced each item into sections that could be moved safely across the floor. These sections were transported using pallet jacks, hand carts, and platform carts.

From there, the dismantled material was moved through the service elevator to the laydown area outside the powerhouse. This staged approach helped keep the work organized and reduced unnecessary handling inside the facility.

For utility and contractor teams, this is an important part of project planning. Removal work often depends on the available path from equipment location to loading area. Elevators, door widths, floor ratings, turning radius, staging space, and containment requirements can all affect how the work should be performed.

Containment and Staging Before Transport

After dismantling, the equipment was placed inside a containment berm until it was ready to be loaded onto a trailer. The material was then shipped to Transformer Technologies’ Salem facility for further processing.

Containment and staging are critical on projects involving oil-filled electrical equipment or equipment with residual materials. Even when units are being dismantled for removal, the work area still needs to be managed with attention to housekeeping, environmental controls, and site safety.

Why This Matters for Utilities and Electrical Contractors

For utilities, municipalities, industrial facilities, and electrical contractors, equipment removal can become complicated when transformers, PTs, CTs, regulators, switchgear, or related electrical assets are located in hard-to-access areas.

A qualified removal partner should understand how to:

• Evaluate equipment size, weight, and access limitations.

• Plan dismantling around the actual jobsite conditions.

• Use cranes, hoists, lifts, carts, and other handling tools appropriately.

• Manage material movement without exceeding floor load restrictions.

• Stage materials in a controlled area before transport.

• Move equipment to a facility capable of further processing.

This project shows how planning and field execution work together. The safest route is not always the fastest route, and the right removal plan depends on the building, equipment, access points, and site requirements.

Experience in Electrical Equipment Removal and Processing

Transformer Technologies supports utilities, electrical contractors, and industrial customers with electrical equipment removal, transformer recycling, oil-filled equipment processing, and downstream material recovery.

Projects like this require direct field experience with electrical equipment, dismantling methods, load handling, transportation planning, and facility-based processing. In this case, the equipment was removed from a challenging powerhouse location, staged in containment, transported off site, and sent to the Salem facility for additional processing.

Planning a PT, CT, or Transformer Removal Project?

If your team is preparing for electrical equipment removal, early planning can prevent delays and reduce risk. Before work begins, it helps to identify:

• Equipment type and estimated weight.

• Inclusion of oil or residual material.

• Access limitations inside the building or yard.

• Available lifting and handling options.

• Floor load ratings where applicable.

• Staging, containment, and trailer loading areas.

• Final processing or recycling requirements.

Transformer Technologies works with utilities and electrical contractors to plan and perform removal projects based on site conditions, equipment type, and downstream processing needs.
