GE transformer buyer's roundup — Myth you hear on job sites: “A transformer is a transformer—as long as the kVA matches, it’ll handle generator feed just fine.” Reality: A generator’s voltage waveform is typically noisier (higher harmonic… [...]

GE transformer buyer's roundup — Your shelter's AC unit is undersized. The transformer sits in the same enclosure, and every watt it sheds as heat must be removed by that already-marginal cooling. [...]

GE transformer buyer's roundup — Every facility manager I talk to starts with the same assumption: buy a transformer rated for my load, and it’ll handle the load. That’s true only if the load behaves like a perfect resistor. [...]

GE transformer buyer's roundup — I've seen too many facility managers buy a 75 kVA transformer based on the first-line price — and then watch the electric meter spin an extra $3,600 per year because they ignored no-load loss. [...]

GE transformer buyer's roundup — You have a 75 kVA continuous load that draws 58 A at 480 V — call it 48 kW real, PF ~0.85. The budget says buy a 75 kVA transformer. [...]

GE transformer buyer's roundup — Most facility managers assume that a transformer's KVA rating is the only number that matters for a panel that gets infrequent attention. That belief is wrong in a way that costs real dollars and downtime. [...]

GE transformer buyer's roundup — You just signed off on a 150 kVA GE Type QL for a new office wing. The load schedule says 118 kVA, the transformer is rated 150, and the factory test sheet shows 97.8% efficiency at full load. [...]

GE transformer buyer's roundup — You’ve heard it a hundred times: “A transformer is a hunk of iron and copper — it’ll outlast the building.” That’s true only if you define “outlast” as “still humming while your energy bill bleeds out and your… [...]

GE transformer buyer's roundup — Every facility engineer who has ever sized a 150 kVA transformer for a half-loaded panel knows the moment of doubt: the unit is 97% efficient on the nameplate, but the enclosure is warm and the electric bill… [...]

GE transformer buyer's roundup — You install a 150 kVA dry-type transformer for a lighting panel that draws 95 kVA. Two years later a production line gets added—now the same transformer sees 135 kVA, plus harmonics from VFDs. [...]
