Thanks to all who responded to my question about broadband radiation from ac
induction motors.

The need for snubbers on the relays?
I dealt with a product which used a 1 1/2 HP motor
with arcing visible to the operator and did have any
high end emissions. 600 MHz is rather high for a
motor. Even 30 MHz. Would have thought problems
showing up in the conducted side of things instead.

Corona discharge can occur when air is electrically
stressed near its break down limit and this will generate
broadband RF energy.
If you have small bubbles of air in a insulator with a fairly
high dielectric constant in an electrical field it produces an
effect known as dielectric focusing and
