Frequently Asked Questions
What secondary current can your rectifier transformers handle?
We design rectifier transformers with secondary currents up to 10,000 A. That sits in the middle of the normal industry band: chlor alkali units commonly run near 40 kA DC and aluminium potline groups between 25 kA and 100 kA.
How do you control harmonics in a rectifier transformer?
Through multi pulse phase shifting, typically a 12 pulse base with units paralleled to reach 24, 36 or 48 pulse. Extended delta phase shifting on the grid side suppresses the 5th, 7th, 11th and 13th harmonics, and split windings on the valve side reduce DC ripple.
What information do you need to quote a rectifier transformer?
DC voltage and DC current, the rectifier topology and pulse number, duty cycle, ambient conditions, harmonic limits, the cooling medium available on site, and the standards the installation has to meet.
Do you build rectifier transformers on an OEM basis?
Yes. We build to your drawings and brand under OEM, or take the duty and site conditions and carry out the full design under ODM. Both routes support third party inspection and witness testing.
