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.

MCL-400IR+ -
MULTI MEASURING INSTRUMENTS Co., Ltd.
・About Ior Leakage CurrentRecently, the leakage current clamp meter is widely used for insulation control of low voltage circuit as the supplementary method of the insulation resistance measurement. The control of leakage current has the advantages to enable the prediction of insulation condition in the electrical power line without having to shut off the power. The leakage current (Io) includes the capacitive leakage current (Ioc)originated in the capacitance and the resistive leakage current (Ior) originated in the insulation resistance each related to the ground. It is considered that the measurement of resistive leakage current (Ior) is the very useful and effective method for the insulation control of low voltage circuit. However, it was difficult to measure the resistive leakage current (Ior)with traditional leakage current clamp meter. MCL-400IR new digital clamp tester enabled the measurements of the resistive leakage current (Ior)without voltage input(phase detection).

Exponential Power
Exponential Power introduced the first digital battery hydrometer to the U.S. stationary battery market in 1988. For over 30 years, Exponential Power has sold and serviced thousands of hydrometers and continues to provide the newest technologies in battery maintenance equipment today. Hydrometers (density meters) measure the specific gravity of a battery’s electrolyte. Based on the specific gravity, the user can determine the state of charge of the battery. Retaining these hydrometer readings and data over time is recommended by IEEE as part of any Battery Maintenance Program. Digital hydrometers are commonly used in utilities, telecommunications, industrial, food and beverage, petrochemical and other applications. In contrast to the old bulb-style hydrometers of the past, our digital hydrometers provide accurate recording, storage and transfer of battery data to a PC -- eliminating hours of hand recording and entering data. As a result, time spent on battery maintenance is reduced significantly.

Analog Devices Inc.
Analog Devices offers RF Front-End ICs for phased array antenna solutions. These RF Front-End ICsare placed right at the antenna element and can quickly switch between transmit and receive functions in radar applications. The power amplifier on the transmit side is highly efficient operating in short pulse durations. The low noise amplifier on the receive side has a low noise figure with high linearity so that it won’t distort the incoming return signal. The RF Front-End IC also incorporates a high performance switch to toggle between the transmit and receive paths. Highly integrated planar phased array antennae need small form factor solutions, and Analog Devices has integrated the switch, low noise amplifier, and power amplifier into a small surface mount package as well as the decoupling capacitors, providing an optimal solution.

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.
