Can transformers be operated above a 1000m/3300′ altitude? transformers have operating losses, and heat is the product of these losses. Hammond low temperature rise transformers are designed with reduced 115°C or 80°C full load operating temperature rises. These units decrease total operating losses by 20% and 35% respectively, compared with the standard 150°C rise operating system.Get Price
