Top 10 Costliest Mistakes In SCR Power Controller Design: Part 5

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.
