Ravanelli ran the show as Derby took a grip of proceedings in the first half, Andy Oakes then kept us at bay during our best spell following Matt O'Hallaran's red card at the start of the second half before two late strikes added extra gloss to the scoreline.
The Italian striker orchestrated most of his side's best play, dropping deep to good effect and rarely wasting a pass.
But he wasn't involved in either of the Rams clinically-taken goals in the first half.
The first came after just five minutes as Marcus Tudgay crossed low from the right and Adam Murray controlled and turned in the same movement before sliding past Rob Burch from eight yards.
The second was a bolt from the blue on the half-hour. Another cross from the right appeared to be going nowhere until Lee Holmes met it first time on the left side of the area and arced a fine volley into the opposite corner.
Ben Thatcher also had to clear off the line as the home side enjoyed the lion's share of possession.
Rohan Ricketts had a couple of chances between the goals. First he found a yard of space in the box from the energetic Ben Bowditch's cross but fired straight at Oakes and then broke onto a loose ball but couldn't quite get away from two or three defenders in pursuit and his effort was blocked by Barry Molloy.
The second half took a dramatic twist after only four minutes when O'Halloran, already booked for his part in an altercation with Steffen Freund, was sent off for diving on the edge of the box.
That naturally led to an increase in possession but we were denied the goal we craved to get back into the game by a brilliant couple of saves from Oakes in the space of seconds after 57 minutes.
Both came from John Jackson corners met first by Bowditch at the near post, the pick of the saves, a superb reaction effort and from the resulting corner, Oakes was there again to tip over Alton Thelwell's header.
Chances came at both ends in the final quarter. Ravanelli somehow missed the target from six yards, Freund got in on the blind side but drove across goal, Galbraith's miscued cross had to be tipped over by Oakes and Burch did well to deny Tudgay one-on-one.
But it was Rams who grabbed the vital third goal with seven minutes left as Ravanelli held the ball up in the box before squaring for Murray to slide home.
Substitute Lee Wilson completed a night to forget with a late volley from the edge of the area.
