Due largely to its air cooled design, the actual mechanics of servicing a dry-type transformer are relatively easy and can be conducted by anyone with

Due to the high safety rating of dry-type transformers, they are often installed indoors in relatively dust-free environments. At the same time, however, they are

Regular maintenance on dry-type transformers ensures that there is no dust build up that undermines the air cooling process. Every transformer is designed to run

While the maintenance of a dry-type transformer is much easier than that of oil cooled conventional transformers, it does require certain limited resources. In some

An important part of the servicing of any transformer – including dry-type units – is the checking of termination points. These are required to be

As dry-type transformers are cooled by air rather than oil, the maintenance process is simple, quick and cost effective. Conventional oil cooled transformers need to

Running cost is essentially the cost of electricity, measured in kWh. These costs are affected by the efficiency of the transformer. All transformers have both

To reduce the risk of unplanned downtime, the maintenance of a transformer needs to include a regular check of its instrumentation. This includes testing of

Dry-type transformers – which are cooled by air rather than oil – have a much lower maintenance cost than their oil cooled equivalents. Oil samples

In addition to its upfront capital cost, transformers also incur a cost for installation and for ongoing operation which is their running and maintenance costs.

Yes, dry-type transformers are generally considered low maintenance compared to oil-immersed transformers. The main reason for this is that they do not require oil for

Yes, dry-type transformers can be used in constrained spaces. One of the advantages of dry-type transformers is that they are compact and lightweight, which makes
