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.

IBEKO Power AB
DV Power has released a new generation of circuit breaker test equipment for condition assessment of medium and high voltage circuit breakers.Field-portable instruments with standalone or PC controlled functionality, allow performing various tests during circuit breaker manufacturing, commissioning and maintenance stages.Applications supported by the DV Power test equipment include measurements of:Contact resistanceDRM (dynamic resistance measurement)Coil resistance and coil current (IEC 62271-100)Mechanism charging time (IEC 62271-100)Minimum trip voltage (IEC 56, ANSI C37.09)Undervoltage release (IEC 60694)The timing of a circuit breaker’s main, auxiliary and pre-insertion contactsSynchronization between the contactsMotion and velocity“First trip” testThe essential part of a circuit breaker condition assessment is the ability to compare the latest test results with the previous testing. Accordingly, our instruments store measured values and compare them to a manufacturer’s limits. Also, a fingerprint obtained in this way can be used at a later stage as a reference during subsequent measurements. In order to obtain an accurate comparison, the tests need to be performed using identical test parameters. Consequently, any deviation and change in the test results may indicate the circuit breaker condition deterioration. Even more, to overcome this issue, DV-Win enables test plans and graph overlay features.Finally, as a final result of a circuit breaker maintenance process, the DV-Win provides analytical tools and customized report creations.

GT658PCI -
Guide Technology, Inc.
GuideTech’s GT658PCI is an ultra-fast, high resolution, DC – 400 MHz Time Interval Analyzer (TIA), ideal for most PC-based lab bench (timing) test applications. What makes the GT 658 superior to traditional counters is analogous to the difference between volt meters & digital scopes. While both measure voltage, the scope provides much more information about the dynamics of the signal. This is because our patented TIA substantially increases measurement speed, and the measurements are displayed as afunction of time. All of these features, along with the benefit of ‘continuous time correlation to a common reference between all measurement time stamps,’ enable our TIAs to make measurements that weren’t previously possible with traditional counters.

Precise Time and Frequency, Inc.
To complement the range of high quality frequency and timing references, Precise Time and Frequency, Inc. has now introduced a new version of the ptf 1226A Auto Switch that includes an additional switch channel (now 3 channels total) of RF, and/or Digital, and/or Time Code, Auto Switching, and a full Ethernet/RS232 remote monitoring/control interface.In addition to the auto switching capability, the new ptf 1226 delivers up to thirty six channels of RF, Digital or Time Code frequency and/or timing references to critical applications such as Satellite Communications, Broadcasting, WiMax and others.Analog channels include a unique output level monitoring feature to provide remote indication of rms voltage output level.The unit can accept up to three pairs of inputs (usually from separate primary and backup sources), and provides monitoring of both the inputs and outputs for signal integrity. In addition RF channels include analog level monitoring. If the primary input on any auto switch channel fails, the unit will automatically switch to the backup input and indicate a primary signal fault.Full remote monitoring and control via RS232 and Ethernet interfaces includes telnet, http (web browser), and SNMP protocols.

Edmund Optics Inc.
These high stability variable frequency optical choppers each include a set of chemically blackened photoetched chopping discs. The mini chopper is an excellent choice for applications requiring a compact package. The chopping discs come in a variety of slot apertures and allow operation. Beam diameter is limited to 0.75mm when using the 200-slot disc and 1.0mm when using the 40 slot mini disc. The easy-to-interchange blades are made of non-magnetic, half hard brass and can be used in combination. Chopping frequency is set by adjusting a ten-turn dial or by applying an external DC voltage to the BNC input. Reference output is a TTL pulse and is in-phase with chopping action. The 5 digit led display gives a direct read-out of the chopping frequency. Power: 90-130V or 180-260V; 50/60Hz; 12VA max. Power supply included. Choppers are often used together with lock-in amplifiers.
