-> High Power Transformers (>100KVA)
When making an enquiry for transformers rated up to
100KVA the specification details requested are usually
quite basic, limited to the minimum fundamental specification
requirements
Input Voltage
Output Voltage
Taps
Rating
Vector group
Other parameters such as Insulation class, Operational
core saturation level, Temperature rise etc are left
to the standard design format we use routinely for our
products. This has enabled us to prepare the product
range data for transformers up to 100KVA.
Above 100KVA it is often the case that these other
parameters are specified more rigorously, under such
circumstances a 200KVA transformer for one client will
be somewhat different in size to a 200KVA transformer
for another depending on the specific limits that are
set for these design parameters. For this reason transformers
with ratings over 100KVA are designed and quoted to
the individual enquiry. Please use our Enquiry page
to specify your requirements.
