20Hz Generator
Signals & Systems India Private Limited
In order to implement a 100 % stator earth fault protection based on subharmonic injection, a 20Hz voltage is injected into the generator star point. The 20-Hz generator SGEN-1001 is used in combination with the Band Pass Filter SBPF-1001 in the Stator Earth fault protection. The injection can be performed by connecting the SGEN-1001 and the SBPF-1001 to the load resistor of an earthing or neutral transformer. If an earth fault occurs in the generator star point, the 20 Hz voltage drives a current through the fault resistance. From the driving voltage and the fault current, the protective relay determines the fault resistance.

Battery Fault Insertion Unit
The Battery Fault Insertion Unit (FIU) provides intelligent switching of cell-simulation channels for the Battery Simulator 1200. The switching capability enables simulation of open-circuit and short-to-rail fault conditions on any cell channel for the purposes of battery management system (BMS) testing. Additionally, a four-wire auxiliary input allows you to connect an external digital multimeter (DMM) instrument to any cell channel for very high-accuracy bypass current and cell voltage measurements. Each FIU provides 24 independently-programmable cell-switching channels for one or two 12-cell Battery Simulator 1200 units. Additional Battery Simulator 1200 and FIU instruments can extend functionality up to 120 series-connected cell channels.

Fault Locating
Schweitzer Engineering Laboratories, Inc.
The built-in fault-locating methods in SEL devices allow you to quickly identify faults, dispatch crews for repairs, and restore service faster. Traveling-wave fault-locating technology calculates the locations of temporary and permanent faults by measuring the arrival times of the naturally occurring traveling waves caused by a transmission line fault. Accurately detecting these waves requires ultra-high-resolution monitoring, and locating is accurate to within one tower span (±300 m). Impedance-based fault-locating technology calculates fault locations by detecting changes in line impedance as a result of a fault. Impedance-based locating is reliable and accurate to about 2 percent of a line’s total length.

Fault Locator
VM-510FFL+
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.

Earth Tester
TAURUS PRECIOHM ET
The TAURUS PRECIOHM ET is one of the specially designed products by TAURUS to measure earth resistivity and earth resistance in a power station. These tests are performed based on 4 point (Wenner) and 3 point (fall of potential) methods respectively. All electrical equipment in the substation and power stations are electrically connected to station earth mat with earth electrodes. The earth electrode ensures that in the event over voltage on the system due to system fault or lighting discharges etc., the parts of the equipment which are normally ”dead” as far as voltages are concerned; do not attain dangerously high potentials. An earth electrode will only be effective so long it has a low resistance to the earth and can carry large currents without deteriorating. Thus the resistance of earth electrode should be low to give good protection and it must be continuously measured and monitored in all the substations and power stations.
