Bender Monitors Protect Offshore Power Supplies

Literature Available Line isolation monitoring (LIM) has proven to be extremely effective in reducing costly downtime from overload in isolated power systems.

Bender, Incorporated of Haverford, Pa., has developed a system said to be ideal for dc power supplies on offshore platforms and other unmanned facilities.

The Bender system integrates a line isolation monitor, a main relay, individual relays for each distribution circuit, and a transducer. This system continuously monitors insulation resistance to earth; sounds an alarm at pre-set, adjustable resistance levels; identifies faulty circuit( s); and determines positive, negative, or symmetrical quality of fault(s).

In addition, the transducer's built-in monitoring circuit provides advance warning to the LIM itself.

Optional under/over voltage relay and dc/dc converter are available for additional protection and ease of maintenance. The Bender dc LIM system is designed for modular installation conforming to Eurocard specifications. Plug/ socket connectors are 15-pole rated at 15 amps each, for easy installation.
