jraef,
Being less expensive and actually working are two different things! This is eng-tips not sales-tips! By drawing less current, there will be less loading on the alternator and prime mover = closer to rated voltage and frequency. BTW, Autotransformer starters are available at this power...
I'm a bit surprised that no-one has suggested the trusty Autotransformer starter? It has the added advantage of the transformer effect (ie. VA in = VA out), and it will not trip on any supply frequency issues.
An Autotransformer starter will (generally) provide more torque at lower current...
Hi all,
I'm new to this site...please be gentle!
Is there a "rule of thumb" for air conditioning operating cost based on the amount of cooling required? I'm trying to evaluate how much it will cost (for electricity) to operate an A/C to cool 60kW of heat in a sealed room.
Any help is greatly...
