driver.SwitchTo().Frame(detailFrame);

ERROR :

Answer 1

You should try below

driver.SwitchTo().Frame("Principal");
driver.SwitchTo().Frame("Header");

No need to switch frameSet. you can directally switch to Header frame

Answer 2

You should try the following change and it should work. Change

IWebElement detailFrame = driver.FindElement(By.XPath("//*[@id='frmSet']"));

to

IWebElement detailFrame = driver.FindElement(By.XPath(".//frameset[@id='frmSet']"));
