AR700 -
Scope T&M Pvt, Ltd.
PD Defect Location in High-Voltage Equipment Insulation by Acoustic Sensors To act on deteriorating insulation the source of PD must be known.The insulation defects produce partial discharges, which emits electrical impulses, radiation of electromagnetic waves as well as acoustic signals.The AR700 measures acoustic signals with multiple sensors spread over the transformer. Then the software determines the failure location using the time difference of all incoming signals. Finally, these coordinates are shown in a 3D model of the transformer. AR700 device is used for measuring of acoustic signals on the external surfaces of gas-insulated breakers and substations, power transformers and other tank high-voltage equipment. The acoustic signals are caused by partial discharges in the insulation, which is the sigh of the defects.The advantage of “AR700” device is the quick installation of the acoustic PD sensors on the external surface of high-voltage equipment tank. The sensors have magnetic holder that is why there is no need to de-energize the equipment for the sensors installation. “AR700” device has 4 syn-chronic channels for acoustic signal measurement. This gives the possibility not only to find the defects in the insulation, but also to locate them. The location function of the “AR700”device is unique for acoustic devices.

IBEKO Power AB
Making a product “safe” requires an understanding of “hazards” that exist in each electrical product. Electrical shock is one of the four fundamental hazards. Because of that, it must be a part of any product electrical safety evaluation. Even though a product requires an electrical power source and uses electrical or electronic components, it should not present an electrical shock hazard to the user.Ground bond or earth continuity testing prevents electrical shock hazards. Similarly to a fault to earth, test instruments generate a high current. The standard requires that the resistance between protective earth and any conductive surface on the equipment does not exceed 0,1 Ohm. The test is performed by applying a DC current between the conductive surface and protective earth. By measuring the voltage drop, it calculates the resistance.RMO-E instruments are ideal for testing the protective bonding (grounding) of equipment following the standard IEC 61010-1. Applying current up to the value of 100 A and the ability to provide in the Contin menu (continuous operation) test current for the pre-set test duration (equal or exceeding 1 min) gives a user a possibility to easily check the protective bonding/grounding of the equipment. The full load voltage of 12 V assures proper measurement and accurate result. Finally, an instrument displays pass/fail classification according to user-preset parameters.

Maury Microwave Corporation
Maury manual tuners are based on precision slide screw technology that utilizes broadband slab line transmission structure and passive probes to create impedances for devices. The probes are designed to be very close to onequarter wavelength in the linear dimension at the mid-band of each range. Since each tuner has two probes, this results in improved matching characteristics for each unit. Another key feature of this series of tuners is the inclusion of a LCD position readout of the carriage position on those units operating below 18 GHz. Higher frequency tuners utilize a micrometer carriage drive. The positional repeatability and high matching range of these tuners make them ideally suited for use as a variable impedance source in applications like device characterization. Such measurements depend upon the ability of the tuner to establish impedances out near the edge of the Smith chart and to reproduce the electrical characteristics as a function of mechanical position. The tuners in this series are also easy to use due to the nearly independent electrical results of the mechanical motions. The depth of penetration of the probe into the transmission line determines the magnitude of the reflection, while the position of the probe along the line determines the phase. While there is some interaction, the effects are almost independent of each other. https://www.maurymw.com/images/mw-rf/mst982e35.jpg

AG-51 -
Potomac Instruments, Inc.
The AG-51 Audio Generator contains a low distortion 20 Hz to 200 kHz sine wave generator, an SMPTE standard intermodulation signal generator and a fixed frequency sine wave generator at 3.15 kHz for wow and flutter tests. Signal outputs are simultaneously available at levels of up to +20 dBm (equivalent sine wave power for complex signals) at separate left (L OUT) and right (R OUT) output connectors. Outputs may be selected for left (L) only, right (R) only, left and right in phase (L+R), and left and right in phase opposition (L-R). Fully balanced or unbalanced outputs at impedance levels 150 ohms or 600 ohms are front panel selectable. Three precision attenuators (10, 1.0 and 0.1 dB) provide a dynamic range of 99.9 dB in 0.1 dB steps. Attenuator dials display the output level directly in dBm in the 150 ohm source impedance configuration. Automatic output leveling circuitry with a built-in self-test feature provides a constant output level thereby eliminating the need for output metering. In the TEST mode the generator output level is reduced to zero, a useful feature during noise measurements.

M4KSerialPlus -
Excalibur Systems, Inc.
The M4KSerialPlus is an enhanced serial interface module for the multiprotocol Excalibur 4000 family of carrier boards, that includes several advanced features such as a high baud rate and high throughput. This module supports up to four independent channels of serial communications, each of which can be selected as RS-485, RS-422 or RS-232. The module operates independently of the host computer, reducing the need for host intervention.The M4KSerialPlus module is based on the Exar XR16M570 Universal Asynchronous Receiver/Transmitter (UART). The device is compatible to industry standard 16550 UARTs. Each of the M4KSerialPlus’s four channels contains a transmit FIFO capable of holding up to 16384 bytes and a receive FIFO capable of holding either 16384 receive bytes or 5460 bytes with a 32-bit Time Tag associated with each byte. These large buffers allow application code to transfer large quantities of data with a single non-blocking subroutine call. The 32-bit Time Tag on receive channels is very useful for synchronizing serial data with data from other modules on the 4000 board or on other interface boards. Each channel has a programmable baud rate of up to 10 Mbps and can be configured as RS-232, RS-422 or RS-485.The M4KSerialPlus module is supplied with C drivers, including source code.
