Short Buddy helps you find the short! This unique tool connects at the fuse panel and becomes in series with the test circuit. A system of audible beeps helps you find the problem and permit hands free troubleshooting. Have a dead short? Short Buddy gives you continuous re-set/re-power capability, a real time saver. While you push, pull, tug and grab wires, Short Buddy is always watching the current level. If your tug causes the dead short again, Short Buddy opens the circuit for 10 seconds, then re-applies power to the circuit. Re-powering the circuit can also be done manually.

Crowbar resistors are three phase resistance banks which are connected to the rotor windings of the DFIG (Doubly-Feed Induction Generator) such as wind power generator. They are used to prevent damage to the inverter circuits attached to rotor side when a fault occurs in the grid. DFIG power converter, which has a restricted over-current limit, needs special attention during faults in the grid. If the rotor current or DC link voltage reaches the threshold value, crowbar resistors disconnect the converter in order to prevent the generator turning into a squirrel cage induction machine. By crowbar resistors, the DFIG could stay connected to the grid and continue its operation.

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.

ILC -
AOSense
AOSense has developed a compact Integrated Laser Controller (ILC) that can be paired with our External Cavity Diode Lasers (ECDLs) to control laser current, piezo transducer (PZT), and temperature. The ultra-low noise electronics are fully digitally controlled. The ILC dimensions are only 5″x2.9″x0.95″. We provide software with an easy-to-use graphical user interface (GUI) that can control multiple lasers from a single window. If preferred, commands may be sent over a USB virtual COM port. The software screenshot below (click the image to enlarge) shows the interface including a plot of the temperature (green line) as it settles to a commanded value.

TWA Standard Series -
IBEKO Power AB
When it comes to winding resistance measurement on three-phase power transformers and autotransformers, TWA Standard series offers some of the most technically advanced instruments with LCD display in the market. Both models are capable of testing six transformer windings with a one-time cable connection, as well as three-phase automatic transformer demagnetization. The stored magnetic energy is safely automatically discharged at the end of the test. The built-in tap changer control unit enables automated test mode, where the instrument operates the tap changer without operator input and records winding resistance results based on pre-selected stabilization criteria. This option makes the operator’s job significantly easier.Both models can output test currents from 5 mA to 25 A DC for the purpose of winding resistance measurement. TWA40D has a special test mode for checking the synchronization of on-load tap changers with three phases simultaneously tested in parallel, in which the total test current can rise to up to 40 A DC.TWA40D has additional advantages when it comes to non-intrusive tap changer analysis. The unique DVtest method enables checking the moving contacts of on-load tap changers during the transition, measuring the transition time, detecting open circuits, and many other types of faults. It is performed with 0.1 ms sampling rate, simultaneously with the measurement of tap changer motor current which helps with the detection of motor and mechanical issues. A special proprietary algorithm is used for testing tap changers connected through a built-in series (booster) transformer. The DVtest can be performed either on one phase or on three phases simultaneously. It can also be performed as an additional test simultaneously with the winding resistance test in all tap positions.An additional unique advantage of TWA40D is the capability of simultaneously testing the winding resistance of all three phases of a three-phase transformer (connected in a YN configuration). This can significantly shorten the total testing time – for example, it enables the operator to perform 33 measurements instead of 99 on a tap changer with 33 tap positions.The test leads for TWA three-phase transformer winding ohmmeters are interchangeable with the TRT turns ratio testers, which means that both sets of tests can be performed with a single test lead connection to the power transformer terminals.

SX set -
Langer EMV-Technik GmbH
The SX1 set consists of 3 passive near field probes for making measurements in the development phase of E-field and magnetic field with a high clock frequency in the range from 1 GHz to 10 GHz. The probe heads of the set SX allow for measurements close to electronic assemblies, e.g. on single IC pins, conducting paths, components and their connectors, to localize interference sources. Field orientation and field distribution on an electronic assembly can be detected through trained use of the near field probe. The near field probes are small and handy. They have a sheath current attenuation and are electrically shielded. They can be connected to a spectrum analyzer or an oscilloscope with a 50 Ω input. They have an internal terminating resistance.
