ISOSCAN® EDS440 Series
- Automatic ground-fault location in ungrounded AC/DC systems
- Locates ground faults while the system remains online
- Compatible with industrial (iso685-D-P) and medical (LIM2010) applications
- Up to twelve channels scanned in parallel, interconnect additional devices to add more
- Uses current transformers, available in a wide range of sizes and shapes
When combined with Bender's ground-fault detectors and current transformers, EDS440 modules locate ground-faults in ungrounded AC and DC systems. Using a special measurement signal after a ground fault is detected, up to twelve separate channels are monitored in parallel to identify the corresponding branch or circuit. Multiple EDS modules may be interconnected to expand the quantity of branches scanned.
Fault location takes place automatically and while the system remains online, negating the need for opening branch circuit breakers or disconnecting equipment.
A complete, installed ground-fault location system requires a ground-fault detector (iso685-D-P for industrial applications, LIM2010 for medical applications) and a single current transformer per circuit or branch. Current transformers vary by application and are available in a wide range of sizes and shapes.
- Used in combination with select Bender ground-fault detectors and line isolation monitors to create an automated ground fault location system in ungrounded AC/DC systems
- Works on single-phase AC, three-phase AC, and DC systems
- Compatible with systems with variable frequency drives and other power conversion equipment
- Monitors up to twelve separate branches in parallel from each individual module
- Uses low-frequency, low-current, line-to-ground tracer signal for fault location
- Channels scanned in parallel
- Uses current transformers available in a wide range of sizes and shapes
- Automated ground-fault location in ungrounded AC/DC systems
- General purpose electrical distribution networks
- Motor control centers
- Control systems
- Isolated power systems in healthcare facilities
