PXI Solid State Switch Module, 6xSPST, 30 A
40-183B-011
The 40-183B-011 has 6 high current SPST switches in two PXI chassis slots. Each SPST switch uses a fully isolated solid state relay which has been designed to offer fast operation under hot switching conditions and high inrush current with no operational life degradation. Each SPST switch can support 30A of continuous current and switch up to 40V signals. The switch can sustain inrush currents in excess of 120A. AC or DC signals can be switched since the switch is polarity insensitive.

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
