Top 10 Costliest Mistakes In SCR Power Controller Design: Part 5Published by ccipower on Fri, 2012-11-16 13:05
Our engineers have compiled a list of the "Top 10 Costliest Mistakes In SCR Power Controller Design." This is our final addition to the series. Read the complete list, and contact us for more information.
#1. Not having a mechanical disconnect
SCRs are not mechanical disconnects and do not provide electrical isolation from the line even when off. This can cost you the ultimate price; your life.
#2. Not having an electrostatic shield in an isolation transformer with an ungrounded load
Without the electrostatic shield, AC can couple across the transformer due to inter-winding capacitance. This results in measuring a potentially lethal secondary high voltage to earth ground.
