Polarity Tester
PT-1
-
International Electro-Magnetics, Inc.
The PT-1 provides a simple and easy way to determine the relative polarity of coil windings. It allows for an in-process test that takes a minimum of time to perform. By placing a coil on the platform and making connection to the start and end of a winding, a test signal is induced in the winding. The induced signal is low level and completely safe for the operator. By comparing the test signal phase of the coil under the test output, the relative polarity is indicated by the Red/Green LED. The tester operates by inducing a signal voltage in the coil under test by means of a magnetic flux field. The field is generated by a coil located in the probe base. The coil configuration is designed to provide optimum field distribution. We have also applied this basic circuit to a 5-channel scanning unit.

CT Polarity Tester
DIR CT
-
SCOPE proudly introduces Dir CT, a CT Polarity Tester specially designed to verify correctness of polarity of current transformers cores in live EHV switchyards. Polarity test is one of the most common yet crucial tests required to be done on current transformers by commissioning as well as maintenance engineers. Even though it is commonly conducted check, there was no all in one simple tool available for this measurement. DIR CT fills this void to perfection, it is expected to significantly reduce the time taken for polarity checks on numerous CT in sub-station, especially during commissioning of new sub-stations

Power modules

G.R.A.S. Sound & Vibration A/S
It provides polarization voltage for the transducer, ensuring that the microphone gets the charging voltage it needs.It provides supply voltage for the microphone preamplifier. The preamplifier acts as a unity gain impedance converter. It provides a certain amount of line drive capability by providing a low output impedance and output current, making it possible to transmit the signal from the transducer to the Power Module without significant degradation.A power module can provide amplification or attenuation to the signal, thus making it possible to fine tune the measurement chain to the signals being measured and the hardware being used.Selectable filters make it possible to exclude unwanted noise from the measurement, e.g. wind induced noise from outdoor measurements.Overload detection makes it possible to validate the measurements and is a useful tool in monitoring setups.When a Power Module with gain is used, you can use longer cables because of the power module's ability to deliver current.A Power module introduces electrical isolation

17 To 19 GHz QPSK Modulator
CCM19001
-
The CCM19001 is a Differential Drive Digital QPSK (Quadrature Phase Shift Keying) modulator operating across the 17.0 to 19.0 GHz frequency range. The modulator utilizes differential drive digital inputs (180º apart) to drive both of the bi-phase modulators (mixers) integrated into the assembly. The modulator is a combination of a matched pair bi-phase modulators, which are in quadrature (90º) to each other. It is modulated by switching polarities of the DC voltage controls in 4 different logic states ("0,0", "0,1", "1,0" & "1,1") for 4 phase states. The QPSK modulator provides constant amplitude, 90º vector: 0 (ref.), 90º, 180º, 270º and operates across the -55º to 85º C temperature range.

Rectangular Horn Antennas
-
SAGE Millimeter wave rectangular gain horns, also called pyramidal gain horns, are offered as both standard and custom models with a rectangular waveguide interface. The pyramidal gain horns only support linear polarization. With a calibrated gain chart, these horns can be used to measure the gain of other antennas by comparing the generated signal levels of both. For this reason, these horns are also referred to as standard gain horns. The listed models offer 23 dB nominal gain, 10/11 degrees typical half power beamwidth and 14 dB/30 dB typical side lobe levels at the center frequency of the band. These horns cover full waveguide bandwidths within the frequency range of 8.2 to 170 GHz. In addition to the models listed below, models with 10, 15, 20 and 25 dB gain and other frequency bands are also available.

Complete Solutions
-
The photoelastic modulator provides unparalleled sensitivity in both polarization generation and polarization measurements. However, there are many non-PEM components in most polarization experiments that can adversely affect your results. The proper selection of detectors, demodulators, light sources and polarizers is crucial to obtaining the quality results that you need and that the PEM makes possible.
