Reduced Voltage Motor Starting Panels by Reactors
A method to limit motor starting current is a series reactor. Iron core or air core reactors can be used for starting purposes. If an air core is used for the series reactor then a very efficient and reliable soft starter can be designed which is more suitable for high MW ratings of synchronous/induction motors at MV levels. The reactors are designed with taps.

High Voltage Differential Probes
A high voltage differential probe is used for measuring the voltage difference between two test points where neither test point is at ground. High voltage differential probes from Tektronix can be used for signals up to 6000 V. These probes are the best choice for making non-ground referenced, floating or isolated measurements in large part due to their common mode rejection capability. These products are designed, manufactured, and serviced by Tektronix.

voltage controlled crystal oscillator
VCXO
A VCXO (Voltage Controlled Crystal Oscillator) is a crystal oscillator the output frequency of which is controlled by adding an external control voltage via a frequency control input on a variable capacitance component such as a varactor diode connected in parallel to a load capacitance (CL). Epson VCXOs are divided into two types according to Voltage-Frequency (V-F) characteristic slopes depending on the AFC (Automatic Frequency Control) input configuration of the VCXO. One is a VCXO with a positive V-F slope and the other is a VCXO with a negative V-F slope. Please note that the input voltage of a control circuit will vary according to the individual type, as shown in Figs. 3 and 4. Epson's VCXOs are capable of either, depending on the customer's preference. Epson's VCXOs have been increasingly used for broader applications such as slave oscillators in phased-lock loops, or frequency modulators. Among the above types, a VCXO combined with a TCXO is called a VC-TCXO , respectively. These components have the merit of delicately controlling their output frequency electrically.

Beijing KeHuan Century EMC Technology Co,.LTD
The KHZ43201 voltage probe is a standard low resistance test probe, which meets the technical requirements for this product in the CISPR16-1 and CISPR14-1 test equipment. When measuring the interference voltage of the power grid, the artificial power supply network cannot be used at the load port, and sometimes it is necessary to use a voltage probe to measure the interference of the signal port, the load port, and the antenna port. The input impedance of the voltage probe to the ground wire is greater than 1.5KΩ, which can protect the input terminal of the receiver.
