Step-down and step-up units paired with a rental generator and its distribution, for turnarounds, new buildings and 480 V equipment in 600 V shops across the Capital Region. Sized with the package and sent from Red Deer.
Around the city, a voltage mismatch tends to come from one of four situations. Each one is solved by putting the right transformer between the power and the equipment, not by finding a second generator.
A plant shutdown near Fort Saskatchewan or in Strathcona County fills a laydown with lunchrooms, tool cribs and offices that all expect 120/208 V. The generator feeding them is often running at 600 V for heavier gear, and a step-down unit lets one supply serve both.
Turnaround & shutdown power →Warehouses in Acheson, Nisku and the city's industrial parks are often finished before the utility connection is live. Temporary power at the building's own voltage lets commissioning and fit-out carry on, and a transformer closes the gap when the available set is built for a different one.
Construction site power →Machinery bought from the United States usually arrives wound for 480 V, while industrial services around Edmonton are commonly 347/600 V. For a trial run, a temporary install or a shop move, a rental transformer between the two keeps the machine working until the permanent arrangement is sorted.
Industrial natural gas generator rentals →When a plant or commercial building takes its own transformer or switchgear out for maintenance, the loads still need feeding at the right voltage. A generator, a transfer switch and a transformer quoted together carry the building through the work.
Transfer switch rentals →It is worth reading the generator's own voltage first: some rental sets run at 600 V and some can be set for more than one voltage. These are the combinations where one usually earns its place.
| Supply | Equipment | Usually needs |
|---|---|---|
| 600 V generator | 120/208 V site trailers and tools | Step-down |
| 480 V generator | 347/600 V switchboard | Step-up |
| 347/600 V building service | 480 V imported machine | Step-down |
| 600 V generator | Both 600 V motors and 120/208 V offices | Generator feeds the motors; a step-down carries the offices |
How kVA is worked out, and the difference between dry-type and pad-mount units, is on the main transformer rentals page. For currents from a known load, the amperage calculator does the arithmetic.
A transformer is chosen alongside the set that feeds it. Energising one draws a short inrush the generator has to ride through, so the two are checked as a pair in Red Deer rather than picked separately.
The package then goes north as one delivery: the generator for the Edmonton site, the transformer, and the panels and cable that carry power to the loads. Who makes the connection, your electrical contractor or someone arranged with the package, is settled at quote time.
Once it is running, field service answers 24/7 at (403) 887-4567. If winter work needs heat as well, a flameless heater can ride on the same truck.
| Both voltages | What the supply delivers and what the equipment needs, phase included. Read them off the nameplates rather than from memory. |
| What it feeds | Just the loads downstream of it, in kW or amps, with any motor or welder called out. |
| Where it sits | Inside a building, in a yard or on a laydown pad through the winter, and how a truck gets to that spot. |
| Who connects it | The site's electrical contractor, or arranged as part of the package. Decide before the quote, not on delivery day. |
| The site's rules | Orientation, permits and anything a Heartland plant asks for before equipment comes through the gate. |
| How long | A turnaround of a few weeks, a winter or a building waiting months for its service each call for a different plan. |
Transformer requests around Edmonton most often come from these communities. A site outside the list is no different: send both voltages, the load and the address.
Ask us. A transformer normally leaves the yard as part of a package, between a generator and its distribution, because that way both voltages are already known and everything is sized as one. If your site already has power and only the voltage conversion is missing, describe the supply and the load, and we will tell you plainly what can be supplied.
No. Every NexSource rental starts in our Red Deer yard, roughly 150 km south of the city. A transformer for an Edmonton-area job is matched to the package there and travels north with it, and delivery is part of the written quote.
Size it for what it feeds, not for the whole site. Add up the loads on the far side in kW, convert to kVA (dividing by 0.8 is the usual planning figure) and allow for motor starts and anything that will be added later. List the loads with the enquiry and we check the sizing against the generator in the same pass.
Often, yes. A generator package at the building's voltage can carry fit-out and commissioning until the permanent service is energised, with a transformer added if the set and the building do not match. The building's electrical contractor makes the connection under the usual permit and inspection rules, so involve them early.
Our transformers are the ones that sit between a rental generator and the loads. Pad-mount units and mobile substations work on the utility's medium-voltage side and are planned with the utility, which inside Edmonton is EPCOR. For work of that kind, tell us about the project and you will get a straight answer on whether we can be involved.
The price is worked out alongside the rest of the package. Its kVA rating, the two voltages, the rental term, the trip from Red Deer and who makes the connection all change the figure, so there is no published rate. The sizing advice is free and the quote comes back in writing.
Send the supply voltage, the equipment voltage, what the transformer feeds and where it will stand. The written quote covers the transformer, the generator and distribution around it, and the trip from Red Deer.
