HRG systems limit the fault current by placing high resistance between neutral point of transformer (or generator) and ground. As it is not possible to locate the fault point in delta connected systems, an artificial neutral point is created and delta connected system can be grounded. This allows a fault current of a few amperes thus locating the fault point gets easy. When the neutral point is grounded thru high resistance, both continuity of operation is provided during fault condition and sufficient current (typically between 2 A and 10 A) flow is provided for ease of locating the fault point.

50-200/201 -
Pickering Interfaces Ltd.
Pickering Interfaces, a leading supplier of modular signal switching for electronic test and simulation, is expanding its range of PCI Fault Insertion switching with the introduction of two new modules (models 50-200 and 50-201) designed for use with differential serial interfaces. PCI Fault Insertion Switch Cards for Differential Serial InterfacesThe new modules include the Differential PCI Fault Insertion Switch (model 50-200) which is designed for lower data rate serial interfaces such as CAN and FlexRay, and the High Bandwidth Differential PCI Fault Insertion Switch (model 50-201) which is designed for higher data rate serial interfaces such as AFDX and 1000BaseT Ethernet. Each module allows the introduction of fault connections that include data paths open, data paths shorted together, and data paths shorted to externally applied faults such as power supplies and ground. The software driver defaults to a protective mode where conflicting faults are prevented to avoid accidentally shorting unintended paths, such as power to ground. A separate mode allows complete freedom in setting fault patterns.

40-204-001 -
Pickering Interfaces Ltd.
The 40-204-001(PXI) and 42-204-001 (PXIe) are single channel differential multiplexers designed to simulate common faults on high-speed two wire communication interfaces such as 1000Base-T1. They are available with support for 1 or 2-channels of two wire serial interfaces. Each channel pair can be looped out to external equipment or the switches can be used simulate a channel open fault. Using the fault bus, switches can simulate a short between both wires or a short to one of two externally applied fault conditions – such as battery supply or ground - via two fault buses.

40-592A-118 -
Pickering Interfaces Ltd.
The 40-592A FIBO (Fault Insertion Break-Out) Matrix Module is a large-scale high density switching matrix based on the Pickering BRIC format. The fault insertion BRICs are designed for applications requiring the simulation of a variety of faults in complex, high pin count, applications involving sensors and control units. Typical faults that can be simulated are open-circuits, short circuits to ground or battery, or short-circuits between input/output lines. Typical applications are in automotive and aerospace industries which involve safety or mission critical systems that have to behave predictably when cabling or sensor faults occur.

VM-510FFL+ -
Vivax-Metrotech Corp
Finding the location of an underground cable fault just became easier with the VM-510FFL+ Standalone A-frame locator. Now locating a suspect cable and finding the fault can be done with the VM-510FFL+ and a compatible transmitter. There is no longer a need for a separate utility locator with cables connecting to it. After connecting a compatible transmitter to the line and placing it in a Fault-Find mode, use the simple to operate four button controls of the VM-510FFL+ to locate and stay on the cable path while pinpointing the sheath or ground fault.

Pickering Interfaces Ltd.
This PXI Fault Insertion module is designed to simulate common faults on two wire communication interfaces such as CAN Bus. This module supports 4 or 8-channels of two wire serial interfaces. Each channel can simulate an open fault in either or both wires, a short between both wires or a short to one of eight externally applied fault connections, such as a battery connection or ground, via four fault buses. Each channel can support up to 0.3A and is rated to handle up to 100V between the wire pairs. The wire pairs have controlled transmission line impedance suited to most differential pair signalling systems, including fast CAN Bus interfaces and RS232. 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.

Pickering Interfaces Ltd.
This PXI fault insertion switch uses solid state switching elements and is capable of switching current up to 10A. It is designed to be able to insert three different fault conditions between the test fixture and the equipment under test: Open-Circuit. Short-Circuit between UUT connections. Short-Circuit to external signals. Through relays on each channel enable signals to the UUT to be set open-circuit. Fault Insertion Buses allow any channel to be shorted to any other channel and also enable any channel to be connected to an external signal such as Power, Ignition or Ground to simulate fault conditions. The module is supplied with 2 fault buses.

PCE Instruments
A cable fault meter can locate open power cables, either live or dead (without current), with voltages up to 300 V. A cable fault meter can locate cables, circuits, short circuits and ground wires. To perform these functions, it is not always necessary to disconnect electrically sensitive devices or to disconnect the power from the cable which is being tested. Many cable fault meter devices can also locate ferrous and non-ferrous metals, wood and plastic with high degrees of accuracy.
