Is A Transformer Effective Protection Against Surges

Hi Guys,

 

I usually put a small surge arrestor on the 230v supply to plc's but on a job at the minute there is no neutral available at the panel so we are having to use a 415v-230v step down transformer for our control supplies. Does this negate the need for a surge arrestor at the plc?
