HIGH VOLTAGE TEST

HIGH VOLTAGE CONSTRUCTION KIT A P P L I C AT I O N The High Voltage Construction KIT is a system of components for applications in high voltage technology. All components have the same length and mechanical interconnections. They can be combined to form a test configuration and are extremely versatile. Test configurations are available which allow the generation of AC voltages up to 300 kV, DC voltages up to 400 kV and impulse voltages up to 400 kV with different output power ratings. Such test configurations are extremely compact and their flexibility allows the test system to be matched to...

G E N E R A L S P E C I F I C AT I O N Design of the high voltage KIT follows nine major factors. These are: • A clear structure is required to ensure that the assembled circuits can be easily checked both by students and theirs instructors. • Rapid set up of the circuit in order to have as much time for active experiments as possible. The assembly of a circuit should not take longer than the connection of a previously equipped high voltage test system. • As few elements as possible should be used in order to maintain the simplicity of the system and reduce replacement parts. A minimum of hardware...

GENERAL REMARKS FOR SETUP The assembly of high voltage circuits using the high voltage construction KIT is quick and easy. An example is the structure of an AC circuit 100 kV (without matching transformer or control unit). Connection Cup Test Transformer Measuring Capacitor Floor Pedestal The configuration is built up by inserting elements to form a self-supporting arrangement. No additional tools are required. Thanks of this simple, but sophisticated design the user can make changes in the circuit quickly and efficiently. That’s especialy an advantage, for combined systems. Every connection...
