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.

Core Loss Testers
S30 and S30S Series
-
Stacks built with punched laminations can have a lot of quality issues. Even though the lamination material is tested in sheet format before any process, that alone is not sufficient to guarantee good quality stators. Wear and tear of the punch, bad welding, bad insulating coating in annealing add to the magnetic losses in the stator. It is always advisable to test the stator core in it's final format before winding to ensure good quality throughout the production batch.

To activate the PLB: Pull the retractable antenna out by its end tab, flip open the spring loaded cover over the activation button, hold the button for 1 second until the lights blink. Visual instructions are clearly printed on the case. When activated, the rescueME PLB1 will transmit accurate position data from its 66 channel GPS for a minimum of 24 hours while the integrated strobe light ensures maximum visibility.Ocean Signal has ensured that rescueME, like all of its other safety products, exceeds statutory requirements. RescueME PLB provides an incredible 7 year battery life, and is covered by a 7 year warranty. Even after more than 24 hours of continuous operation, and when the battery power is insufficient to transmit the satellite signal, the PLB1's homing beacon and strobe light will continue to operate. This high intensity strobe light features a molded lens to enhance the visibility of its efficient LED and it gives a powerful 1 candela light emission.Self-test of the PLB can be carried out with a simple button press with the start of test and results clearly indicated by a green flashing light. The antenna is easily extended like a normal tape measure and can be retracted using the winding mechanism on the top of the unit. This unique feature greatly facilitates user training and familiarization as it is not a one time deployable antenna similar to existing PLBs.rescueME comes with a snap-in mounting bracket and universal rubber mounting strap which can be fitted permanently or with each use.

Single-Phase Transformer Winding Resistance Meters
RMO-TD Series
-
Using the most advanced switch-mode technology available today, the RMO-TD series is ideal for winding resistance measurements of inductive objects. Transformer resistance meters and tap changer analyzers are perfect for testing:transformer windings (power transformers, distribution, autotransformers),all types of tap changers,generators,electrical motors,high-current busbar joints,cable splices,and welding joints.In addition, transformer demagnetization can also be done with all RMO-TD instruments.The RMO-TD series contains 3 models, with maximal test currents from 25 A (RMO25TD) to 60 A (RMO60TD).The three independent voltage sense channels enable testing of three windings in series. This enables measurements of winding resistance in every tap position of an on-load tap changer without discharging between the tests.All RMO-TD transformer resistance meters have a built-in tap changer control unit. It enables remote control of on-load tap changer (OLTC) directly from the device. In order to make the most out of this feature, DV-Win software is included which can be programmed to do everything automatically – running winding resistance tests and changing OLTC tap positions.The DV-Win software also enables control and observation of the test process, as well as saving and analyzing the results on a PC. It provides a test report, arranged in a selectable form as an Excel spreadsheet, PDF, Word, or ASCII format. Additionally, DV-Win measures and calculates the OLTC transition time, the ripple and the winding resistance for each tap changing operation. The software can also perform the calculations necessary for the “Heat Run” test.All results can be exported in the report format.

High Voltage Surge Testers
HVST
-
The most important features of the surge tester are its ability to test the entire winding insulation system. A high voltage surge generates turn to turn, coil to coil, and phase to phase voltage stress, as well as ground insulation stress. When used as a dielectric test, accurate voltage readings are essential. The HV Surge Tester monitors the voltage directly across the winding under test. This voltage is displayed on an oscilloscope and recorded on the Pass/ Fail LED latch monitor. This voltage will be accurate despite the impedance of the winding being tested. The insulation system can be tested way above the operating voltage because of the brief duration of the applied voltage test pulse. This allows faults to be detected long before they become apparent at operating conditions.
