LPI’s insulated joint protector (IJP100) is designed for protection of
insulated joints in oil or gas pipelines. With long lengths of insulated
pipeline, induced voltages in the pipes caused by local lightning or power
line fault activity can be in the order of tens of kilovolts. For protection
against insulated joint break down, LPI developed the IJP100 which is
connected directly across the insulated joint. In its inactive state the IJP
presents an effective open circuit (10¹º Ω) across the joint. Should the
insulated joint voltage exceed the breakdown voltage of 350V, the IJP
will immediately conduct to safely pass the surge current to ground and
thus bypassing the insulated joint. After conducting, the IJP will
automatically reset to its inactive state.
