You only need to use a ballast if your transformer is NOT current limited
as with a pole pig or a potential transformer. Neon sign transformers,
oil burner ignition transformers, and the majority of microwave oven
transformers all have built in magnetic shunts to current limit them and
consequential don't need any ballast.
