Crowbar Resistors
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.

Polarity Tester
PT-1
International Electro-Magnetics, Inc.
The PT-1 provides a simple and easy way to determine the relative polarity of coil windings. It allows for an in-process test that takes a minimum of time to perform. By placing a coil on the platform and making connection to the start and end of a winding, a test signal is induced in the winding. The induced signal is low level and completely safe for the operator. By comparing the test signal phase of the coil under the test output, the relative polarity is indicated by the Red/Green LED. The tester operates by inducing a signal voltage in the coil under test by means of a magnetic flux field. The field is generated by a coil located in the probe base. The coil configuration is designed to provide optimum field distribution. We have also applied this basic circuit to a 5-channel scanning unit.

IL/RL Testing Platform
JW18001
Shanghai Joinwit Optoelectronic Tech,co.,Ltd
To meet the test requirements of MPO devices, we adopt the JW18001 optical device testing platform,JW1608 No-mandrel IL/RL tester module, JW1606 multi-channel optical switch module and form an integrated solution for MPO testing. The application of No-mandrel technique solves the problem that the multi-core optical device can not be winded and needs fiber matching cream, thereby the testing efficiency of the insertion loss and return loss of the multi-core / ribbon fiber has been greatly improved. At the same time, MPO applications can configure a variety of testing mode, test reports, threshold setting function, so multi-core optical device testing is no longer complicated.

Bat Deterrent Systems
As White-Nose Syndrome continues to ravage the populations of many hibernating bat species, the wind industry remains committed to lessening its impact on wildlife, including contributing to bat fatalities. While it is well researched that wind turbines cause mortality to bats, successful minimization methods have been implemented. Presently, the most effective techniques involve curtailment, which requires a reduction in energy generation. NRG Systems understands that this is not an ideal option for wind plant operators, so we have set out to develop Bat Deterrent Systems that could significantly reduce bat take without curtailment, meaning operators can produce more renewable energy more of the time while keeping all bats out of harm’s way.

Three-Phase Transformer Winding Resistance Meters
TWA Advanced Series
TWA Advanced series is the latest DV Power solution for three-phase transformer winding resistance measurement and tap changer analysis. They are capable of testing six transformer windings with a single cable connection, as well as three-phase automatic transformer demagnetization. It has the option of the automated test mode, where the instrument operates the tap changer without operator input (minimizing the risk of human error) and records winding resistance results based on pre-selected stabilization criteria.The unique DVtest method of tap changer analysis 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, together with the measurement of tap changer motor current which detects 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 simultaneously on three phases. It can also be performed together with the winding resistance test in all tap positions.A unique advantage of TWA Advanced instruments 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 speed up the testing– for example, it enables the operator to perform 33 measurements instead of 99 on a tap changer with 33 tap positions.TWA500 is equipped with a large 10.1” graphical touch-screen display, while TWA400 has a 7” graphical touch-screen display. Besides making the interface much more user-friendly compared to older winding ohmmeters, it also enables certain test options that were previously available only with DV-Win software. The most important among them are DVtest, tap changer motor current measurement, “Heat Run” test, test templates, and automatic test mode.
