Product Description
CORRTECH inherited the tradition of the DEI to offer innovative protection products to the corrosion prevention industry, while building off of proven solid-state technology developed by DEI. With a lightweight, metallic housing and lower cost, the SSD can be economically applied throughout a cathodically protected system.
The SSD functions as a DC isolation and AC coupling device (a "decoupler"), preventing the flow of CP current up to a predetermined voltage threshold, while passing any induced AC current. For voltage that attempts to exceed the threshold, the device instantly switches to the shorted mode, providing overvoltage protection. After the event is over, the device automatically switches back to the DC blocking mode. This operation can occur an unlimited number of times, and is typically due to AC faults and lightning, which the SSD is rated for. While the standard threshold is -2V/+2V, the SSD can be supplied with up to a -3V/+1V threshold and several lower threshold combinations.
The threshold is the absolute, or peak, voltage at which switching occurs, and is the sum of the DC and peak AC voltage across the terminals of the device. This results in a very low, and safe, clamping voltage across the SSD terminals.
Applications
The SSD is designed for:
Decoupling gradient control mats (grounding mats) from pipelines.
Over-voltage protection of equipment from AC faults, lightning, and switching transients (e. G. Insulated joints).
Decoupling dissimilar metals that must otherwise be AC bonded for safety.
AC grounding and DC isolation of electrical equipment integral to a cathodically protected system.
Mitigation of induced AC voltage.
The key parameters of the SSD are:
Blocking voltage or threshold voltage.
DC leakage current for a given blocking voltage.
AC fault current rating.
Lightning surge current rating.
Steady-state AC current rating
