Swell sustaining transient voltage surge suppressor

A transient voltage surge suppressor assembly comprising:

• a first energy absorbing device;
• a second energy absorbing device in parallel with the first device;
• and
• a voltage sense circuit configured to take the first device off-line when a voltage swell lasts for at least a predetermined duration.

A transient voltage surge suppressor assembly comprising:

• a first energy absorbing device;
• a second energy absorbing device in parallel with the first device;
• and
• a power sense circuit configured to take the first device off-line when the first device has absorbed its energy absorbing limit.

A transient voltage surge suppressor assembly comprising:

• a first energy absorbing device;
• a first capacitive element wired in series with the first device, wherein the first device and the first capacitive element are wired between a line and a neutral;
• a first pair of relay contacts wired across the first capacitive element, wherein the first relay contacts form a portion of a first relay, the first relay being configured to create a short circuit across the first capacitive element thereby placing the first device on-line, the first relay being further configured to create an open circuit across the first capacitive element thereby taking the first device off-line;
• a second energy absorbing device connected to the line;
• a second capacitive element wired in series with the second device, wherein the second device and the second capacitive element are wired between the line and a ground;
• a second pair of relay contacts wired across the second capacitive element, wherein the second relay contacts form a portion of a second relay, the second relay being configured to create a short circuit across the second capacitive element thereby placing the second device on-line, the second relay being further configured to create an open circuit across the second capacitive element thereby taking the second device off-line;
• a third energy absorbing device wired between the line and the neutral in parallel with the first device, the third device having a higher clamping voltage than the first device;
• a voltage sense circuit configured to detect a voltage swell and take the first and second devices off-line when the voltage swell lasts for a duration and place the first and second devices on-line in the absence of the voltage swell.
