    Tips: Causes leading to the burnout of isolation transformer

    1. There's no fuse on the high and low voltage side of the step up & step down isolation transformer. Some isolation transformers may have equipped with fuse switch or horn fuse, but the fuse is generally replaced by the aluminum or copper wire, which makes the fuse unable to fuse normally and thereof causes the burnout of transformer when low-voltage short circuit or overload.
    2. The high and low voltage fuses of isolation transformers are not properly configured. The fuse on the transformer is generally over configured, so when the isolation transformer is seriously overloaded, the transformer is burnt.
    3. Oil leakage is the most common external abnormal phenomenon of isolation transformer. The transformer is filled with oil, and all joints are equipped with plastic beads and rubber pads to prevent oil leakage. After running for a long time, some plastic beads or rubber pads in the transformer would be aging and cracking and cause the oil leakage, as a result, the insulation will be dampened and its performance reduces, thus leading to discharged short circuit and burning the transformer.
    4. Most of the high and low voltage wires of the 2 kVA isolation transformer are introduced by overhead wires. As the lightning arresters are not timely installed or 10 kV lightning arrester is not installed, the transformer is burned out due to lightning strike.
    5. Some isolation transformers are not configured with primary protection, or they have been configured with primary protection, but the action and reliability of the primary protection are rather low, some even can't act at all.

    2kVA isolation transformer is exactly what I wanted
    As an electrical engineer, I knew exactly what to expect and this 2kVA 1-phase isolation transformer delivered. Aluminum wire winding of the transformer is enough for me, used to step down 240V to 110V. It works great for my electrical trouble shooting!

    ATO Responded
    Yes, sure. Just indicate your detailed delivery address and contact info (Name+Phone).
    Is there any need for concern?
    1. The nameplate has environmental temperature range of -20 to approximately 40degrees C.
    2. And depending on whether the nameplate or the data sheet is correct it can sustain either 180 or 155 degrees C.
    3. Depending if it is class H or F insulation.
    4. I guess there is concern that it is already at 50C and running 2 to 3 AMP. at no load.

    ATO Responded
    The transformer is about 50 degrees Celsius with no load, and the primary current is 2 or 3 A, which is normal, no problem.
    When the transformer is running, there will be a temperature rise. When the internal temperature reaches above 80 degrees, the fan will automatically turn on to dissipate heat. The working temperature -20 degrees to 40 degrees is only the external ambient temperature. When using the transformer, you should be noted to ventilation and heat dissipation, and it should not be used at full load.
    Works great
    This isolation transformer is the perfect solution. I plugged it into my GFCI protected circuit, then plugged the fence charger into the isolation transformer. The fence charger now works as expected and other appliances on that circuit still have GFCI protection. This has worked flawlessly.
