TM510 -
T&M Tools Limited Co
TM510 Surge Generator is mainly used for testing power cable high-resistance and arc-over fault whose grade range is 0-10kV, co-operating with cable fault tester and locating devices to test and locate faults. If the user choose the professional digital milli-ampere-meter, as for cable with grade range about 0- 6kV, the instrument can also be used to do DC&voltage resistance test and current leakage test after the fault is repaired. The instrument is internally equipped with voltage-rise rectifying and discharging device, has complete functions, and is also convenient and safe to be wired and operated.

ASTM D149 -
National Technical Systems
This test method covers procedures for the determination of dielectric strength of solid insulating materials at commercial power frequencies, under specified conditions. Unless otherwise specified, the tests shall be made at 60 Hz. However, this test method is suitable for use at any frequency from 25 to 800 Hz. At frequencies above 800 Hz, dielectric heating is a potential problem. This test method is intended to be used in conjunction with any ASTM standard or other document that refers to this test method. References to this document need to specify the particular options to be used. It is suitable for use at various temperatures, and in any suitable gaseous or liquid surrounding medium. This test method is not intended for measuring the dielectric strength of materials that are fluid under the conditions of test. This test method is not intended for use in determining intrinsic dielectric strength, direct-voltage dielectric strength, or thermal failure under electrical stress (see Test Method ASTM D3151). This test method is most commonly used to determine the dielectric breakdown voltage through the thickness of a test specimen (puncture). It is also suitable for use to determine dielectric breakdown voltage along the interface between a solid specimen and a gaseous or liquid surrounding medium (flashover). This test method is similar to IEC Publication 243-1. All procedures in this method are included in IEC 243-1. Differences between this method and IEC 243-1 are largely editorial. Note: The above information is taken directly from the test method Scope published in ASTM D149.

Analog Devices Inc.
Analog Devices offers the broadest portfolio of low voltage single-supply D/A converters (DACs) in the industry, which includes many leading products in performance and package size. A wide variety of applications use ADI precision nanoDAC® products because of their small footprint and robust range of features, including 8- to 16-bit resolution, low power, a fast 50 MHz SPI or 3.4 MHz I2C interface, and more, in a tiny package option. ADI’s nanoDAC+™ products offer enhanced features such as higher accuracy, improved dc performance, increased robustness, and lower glitch energy, among other advantages.

Accel-RF Corporation
The advanced development of new technologies, such as SiC and GaN, have opened the opportunity for more efficient and higher voltage/power performance in switching and power management circuits. Their high cutoff frequencies, low on-state resistance, and very high breakdown voltages can increase power supply power handling densities approaching hundreds of watts/inch. Reliability of these new technologies and techniques is critical for realizing practical applications. While Silicon devices have a rich history of proven reliability, these newer compound semiconductor technologies are too new to have a reliability history and have not been well proven. Further, process variations, even in well-controlled lines, yield widely varying results. This has driven the need for additional testing and to burn-in devices prior to delivery.

9300 Series -
NH Research, Inc.
NH Research, Inc. (NHR) has released the new 9300 series, a higher-voltage / higher-power version of its popular single-channel 9210 series battery test systems. The 9210 Series provided a 12kW power module operating at 40V, 120V, or 600V and which allowed paralleling with similar systems to increase the power, whereas the new 9300 system provides a 100kW power module with a software-selectable high voltage range (1200VDC / 167A) and high-current range (600VDC / 333A) allowing for efficient testing of single-voltage and double-voltage Electric vehicle (EV) batteries as well as high-voltage Energy Storage Systems (ESS) used in grid-tied applications. The 9300 further extends NHR’s family of high-power battery test and emulation capabilities which are ideal for analyzing a battery performance under xEV drive cycles and grid-storage profiles such as PJM and time-shifting profiles. Like the successful 9200 and 9210 systems, the 9300 modules are independent allowing for testing of multiple batteries, each with a different test plan, power levels and start/stop times. When higher power is needed, the 9300 modules may be paralleled providing 200kW, 300kW or up to 1.2MW capability. This modular power capability allows a system to be sized to the power levels needed today while ensuring expansion capability should additional power be needed in the future.

No. 2J6 -
Knopp Incorporated
When the Knopp Precision Transformer in the 2J6 set is compensated for, and used with, a secondary burden of 15 volt-amperes, for example, the ratio of this precision transformer is well within 0.02% and the phase angle is well within 2 minutes. The transformer, in common with other Knopp Precision Multirange Transformers, is wound so that it has practically the same ratio and phase angle accuracy on all ranges.
