Ground-Fault Detectors for Ungrounded Systems
-
Early detection of ground faults on ungrounded systems allows critical systems to remain online while faults are identified and resolved. By continuously monitoring the system's insulation resistance, Bender's ground-fault detectors can provide early indication of both immediate and trending ground faults before leakage current may be of concern.

Ground-Fault Products for Solidly Grounded Systems
-
Ground-fault products are used to monitor grounded systems (ungrounded and grounded) for fault currents or residual currents. The sum of all conductors except the protective earth conductor is measured by means of measuring current transformers.In general, ground-fault monitors (RCM - residual current monitors) are used to send a message to the user even before reaching the shutdown threshold of the GFCI. Ground-fault monitors detect deteriorations of the insulation level at an early stage and in a reliable way.

Ethernet/AFDX/BroadR-Reach PXI Fault Insertion Switch - 8 Channel
40-201-008
Fault Insertion Unit
This high bandwidth differential PXI fault insertion module is designed to simulate common faults on high speed two wire communication interfaces such as Ethernet. This module supports 4 or 8-channels of two wire serial connections and can be used for simulating faults on Ethernet, AFDX, BroadR-Reach, 100BaseT and 1000BaseT interfaces. Any wire can be set to an open circuit, shorts can be applied across the wire pair, or to the adjacent pair. Fault connections can be made to one of four external signals via two fault buses, typically simulating connections to a supply voltage or ground. Each fault bus is capable of carrying 2A allowing multiple channels to be connected to the same fault condition. Additionally, each fault bus features a changeover relay to allow the user to connect alternative fault conditions to the fault buses.

Variable Power Supply
VS3
-
The VS-3 power supply is a very convenient portable, non-isolated “variable source” from 0 volts to 150 Vac or 0 volts to 150 Vdc and rated for up to 3 amps, thus the name VS-3. It is comprised of an illuminated voltmeter that reads to the first significant digit, AC variable system output voltage, DC variable system output voltage, logic output voltage and one sense (continuity) contact monitoring points. Banana jacks for connection of test leads are spaced at intervals that allow the use of dual banana test plugs if desired. The VS-3 is protected by two levels of overcurrent protection; AC input, and ground fault protection by a GFCI. All circuitry is housed inside a custom designed case made from 16 gauge steel. An Internal fan dissipates heat buildup and exhaust through louvered side vents built into the case. The carrying handle is designed with a “spring return to rest” position and is padded for comfort. The case has been sized for optimum portability and is balanced from the handle during transportation. The case has a powder coated finish that is scratch, chemical and weather resistant. Rubber padded feet support the case when in the upright position and a convenience receptacle is located on the side of the case. A unique feature of the VS-3 is that it contains “Magnet Packs” on the back of the case. These “Magnet Packs” can support the VS-3 and allow it to “hang” from any magnetic metal surface. The VS-3 can be powered by our UPS system, eliminating the need for an extension cord. The ability to magnetically attach the VS-3 near the source of connection and eliminating the need for an extension cord makes the VS-3 a “must have tool” for technicians.
