ALLOY AND PTC CERAMIC BASED LOAD BANKS FOR BATTERY CAPACITY TESTING

ALLOY AND PTC CERAMIC BASED LOAD BANKS FOR BATTERY CAPACITY TESTING

ALLOY AND PTC CERAMIC BASED LOAD BANKS FOR BATTERY CAPACITY TESTING

(OP)
what are advantages of Alloy based load banks for battery testing.actually i am looking for comparison b/w alloy resistors based load banks and ptc ceramic resistors based load banks?

RE: ALLOY AND PTC CERAMIC BASED LOAD BANKS FOR BATTERY CAPACITY TESTING

although alloy and ptc (for small load)both type of resistors are in use for battery load testing; but one needs to be noted that for higher current rating (for higher power rating say greater than 10-15kw) alloy (stainless steel alloy and Ni Cr alloys) resistors are preferabl.
there are no. of advantages of alloy resistors based load banks over ptc resistors based load banks like:
Mechanical - lighter in weight, easy handling/mobilization, durable.
electrical - good of higher current ratings/power rating more than 10-15kw, sustainability, safe discharge, stability etc..
