AC Resonant Test System
Yangzhou Power Electric Co., Ltd
Testing of certain apparatus requires much high voltage or current that a straight AC test system is not sufficient. Thus resonant test reactor with a variable core is needed. The main advantage of such test systems is lower input power and larger output power. The resonant test system is designed to compensate capacitance in the testing circuit precisely by tuning inductance of the test system. AC resonant test system is used for factory testing of middle, high and ultra-high voltage cables, capacitors, generators, motors, power transformers and gas-insulated switchgears.

Magnetic Material Test Fixture
16454A
The 16454A is designed for accurate permeability measurements of toroidal-shaped magnetic materials. Since the construction of this fixture creates one turn around the toroid (with no magnetic flux leakage), the need of winding a wire around the toroid is unnecessary. Complex permeability is calculated from the inductance with and without the toroid. When the E4991A/4291B with option 002 is used as the measurement instrument, direct readouts of complex permeability are possible. In addition, it is furnished with a small and a large fixture to adapt to a wide range of sizes.

General Purpose Basic Carrier Demodulator
CD15
The CD15 Sine Wave Carrier Demodulator operates with variable reluctance transducers to provide a DC output signal for dynamics as well as steady state measurements. A 5kHz sine wave excitation is applied to the two inductance ratio arms of the transducer and the resulting output is demodulated and amplified using the latest integrated circuit techniques. The DC output is obtained from an active filter circuit and gives a uniform response from steady state to 1000 Hz. The low impedance sine wave excitation allows operation with the transducer located over 1,000 feet from the CD15.

Lightning Current Generator
Shanghai Guantu Technology Co., Ltd.
The lightning wave impulse current generator is an impulse current generator that generates a simulated lightning current waveform . Its working process is as follows: first, the transformer charges the capacitor bank through the silicon pile, when the charging voltage reaches a predetermined value, the spark gap is triggered, and the capacitor is discharged through the total inductance and total resistance of the circuit. When the resistance is greater than or equal to the critical damping value, a unidirectional impulse current wave is generated in the circuit. When the resistance is less than the critical damping value, an oscillating impulse current wave is generated. The magnitude of the impact current amplitude is related to the circuit parameters. When the capacitance value and charging voltage are the same, the smaller the inductance value, the greater the current amplitude. In order to obtain as much current as possible, a pulse capacitor with a small inductance value is usually selected, and the total length of the connecting line should be as short as possible when arranging the main capacitor, so that the total loop inductance value can be reduced as much as possible.
