This Pulse Rectifier is a "new generation” cathodic protection power unit designed to protect up to four structures
using one common ground bed. This feature is very attractive where multiple structures., i.e., well casings or pipelines, are in the same vicinity (within 300 meters of each other) and can all be protected from a common ground bed / power supply installation.
Components
The main components of this Pulse Rectifier are as follows:
-
Enclosure (oil immersed)
-
AC Input Section
-
Main Power Transformer
-
Control Module
-
Pulse Modules (1 to 4) per enclosure
-
Control Panel
-
Power Distribution Panel
Features
Serviceability Features
-
On the standard rectifier type enclosure, front and side opening doors are provided for easy installation and servicing.
-
The entire rectifier assembly is built on a slide-out chassis allowing easy removal from the cabinet for service.
-
The major electronic components are enclosed in a single module housing.
-
A pulse interrupt circuit is provided which will function with any portable current interrupter.
-
Temperature monitoring devices are built into the system. These devices monitor critical electronic component operating temperatures. If the operating temperature should exceed a maximum range, the pulse module output will be interrupted until the temperature reduces to a safe operating level. At that time, the system will automatically restart and return to previous operating parameters.
-
For structures that require in excess of 15 amps of protective current, additional rectifiers can be added to the same structure and operated in parallel to provide the required current.
-
For multiple structures at a common location, additional rectifiers may be installed on a common anode ground bed. Each rectifier will provide an independently controlled, constant current to each structure.
