120KVA 125KVA Isolation Transformer

Electrical isolation is necessary to protect circuits, equipment, and people from shocks and short circuits as well as to make accurate measurements. Isolation, also referred to as galvanic isolation, means no direct conduction path exists for the current to flow; no physical connection exists.

An isolation transformer is a transformer that is used to transfer isolated AC electrical power to a device or equipment for safety, protection or to reduce the harmonics and transient voltage surges. It provides isolation between the powered device and power source based on the Galvanic isolation where there is no conductive path between the power source and powered device.

First, clean any dust or dirt from the cooling fans and windings. Use either a vacuum or compressed air to avoid directly touching the components. Ideally, use both methods. Start by vacuuming off the parts followed by spraying them with compressed air that has a pressure of no more than 20 to 25 psi. Only use dry compressed air. Avoid using chemical cleaners to protect the surfaces of the transformer from damage.

Second, tighten all accessible hardware and replace any loose insulation or parts. Doing this prevents screws or nuts from working loose during regular operation.

Lastly, if you need to remove dust from your fan blades or transformer windings regularly, install filters at the bottom ventilation ports. These filters should protect the inner components from dust accumulation, which can reduce the lifespan and efficiency of the transformer. Also, just like the filters in your HVAC units, these filters must be replaced regularly so as not to clog up and restrict air flow into the enclosure in order to help circulate cooler air and exhaust the warmer air.
