Bender ISOSCAN - Model EDS440 Series -Ground-Fault Locator for Ungrounded Systems
The ISOSCAN® EDS440 Series by Bender offers advanced ground-fault location capabilities for ungrounded AC and DC systems. Integrating with Bender's ground-fault detectors and current transformers, this module can identify faults across up to twelve channels simultaneously without disconnecting equipment. Benefit from continuous online fault detection using a special measurement signal triggered upon fault detection. EDS440 modules can be networked for increased coverage, a vital feature for LIM testing to ensure electrical system integrity. Essential components of the setup include a ground-fault detector (iso685-D-P for industrial or LIM2010 for medical use) and current transformers tailored to application needs. This system supports efficient and uninterrupted operation, eliminating system downtime typical of manual fault checks. EDS440 automates fault location processes, maintaining system operations and reducing maintenance efforts, thereby enhancing reliability and safety in critical electrical applications.
- 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. This capability is particularly beneficial for LIM testing procedures, ensuring the integrity and safety of electrical systems. 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. This automated ground fault locator ensures uninterrupted operation in ungrounded systems, avoiding manual checks and downtime.
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, making it an essential setup for comprehensive LIM Testing. Current transformers vary by application and are available in a wide range of sizes and shapes.
