Import Tips

Include ANSI/IEEE C57 standards compliance docs; U.S. utilities require proof of dead-front design

Document dielectric fluid type (mineral vs

FR3 vegetable oil) as it affects environmental permits

Avoid common pitfall of misstating impedance values, which must match nameplate for valuation
