Insulation fault locator - 800 V, 1 - 10 000 kΩ | ISOMETER® IRDH575 series
The A-ISO meter is part of the IRDH575 Series from Bender that is used to monitor the insulation resistance of unearthed power supplies. This device is generally used in 3(N)AC, AC/DC, and DC systems. AC systems may include additional DC-supplied loads like converters or thyristor-controlled DC drives. It shows its data on a backlit plain text display in 4 x 16 characters.

Fault locator for overhead lines - AR-OH
The AR-OH AutoRANGER is a self-adjusting fault indicator applied on overhead systems. It automatically selects a trip value based on sampled load currents. To become active and ready to respond to an event, the AutoRANGER must be installed on an energized line long enough to allow load current sampling and selection...
Fault locator for overhead lines - AR-OH
The AR-OH AutoRANGER is a self-adjusting fault indicator applied on overhead systems. It automatically selects a trip value based on sampled load currents. To become active and ready to respond to an event, the AutoRANGER must be installed on an energized line long enough to allow load current sampling and selection of a trip value. After an event has occurred the AR-OH samples system conditions to determine a display notification of either a temporary or permanent event occurrence.
A temporary event is indicated by a single superbright amber-colored flashing LED. Permanent events are indicated by two superbright, red flashing LEDs. The flash duration period of both event types (temporary or permanent) may be selected to best coordinate with line crew response times. Available flash time periods are noted in the ordering tables.
The AR-OH uses inrush restraint technology to prevent the AR-OH from tripping on reclosing attempts. A true timed reset design provides protection from false trip responses resulting from backfeed currents or voltage fields generated from overbuilt/underbuilt systems. Manual LED test activation or flashing clearing is accomplished using test tool CRSRTT (sold separately).

Earth-fault detector - GFD
Ground Fault Detectors (GFD) are typically installed on three-phase underground systems. GFDs sense a fault by detecting an imbalance in the vector sum of the currents in the three-phase cable. The GFD indicates a fault by showing a large reflective red target (8 square centimeters). GFDs coordinate with current limiting fuses, are available with trip response time settings, auxiliary contacts for SCADA monitoring, and in a variety of reset classes.
GFDs are suited for application in harsh environments.
Detects ground faults by sensing the vector sum of the current flowing through a three-conductor cable.
Choice of three reset options (secondary voltage, load current, or time) to meet various application needs.
Install the split-core sensor on three-phase cables without opening the primary.
Large reflective red target is easy to see both at night and during the day.
Submersible, vinyl-coated sensing core.
Stainless-steel hardware and UV-stabilized materials ensure long product life.
Thousands of SEL GFDs in service today help customers around the world quickly locate ground faults.
