03 · ERECTED ON SITEPower transformer questions.
What is the maximum rating of a Dynamech power transformer?
Dynamech builds three-phase power transformers up to 10 MVA with primary voltage up to 33 kV. Inverter duty transformers for solar plants can be built up to 13.2 MVA.
Which standards do Dynamech power transformers comply with?
Power transformers are designed and tested to IS 2026 and IEC 60076. Designs to ANSI, BS, AS and SABS specifications are available on request.
Which cooling and insulating oil options are available?
Cooling can be ONAN, ONAF or OFWF. Units can be filled with mineral oil, silicone oil, natural ester or vegetable-based oil as per requirement.
Can losses and impedance be designed to our specification?
Yes. No-load loss, load loss and percentage impedance are designed to the customer's specification or tender GTP, and verified by routine tests before dispatch.
