GC 223 Impulse Generator Control Module The system is equipped with an industrial PC which provides a Windows based control software with full visualization of the test procedure, measuring values and warnings or alarms. For more information please contact us. The Generator Control Module GC 223 allows comfortable and flexible control of an impulse generator system. The control system GC 223 is a result of our close collaboration with worldwide impulse test systems users and reflects our experience in high voltage testing of more than 50 years. The hardware of GC 223 is based on well established Haefely in-house developments. Only durable and well protected components, specially adapted to a demanding high voltage environment, have been used. The GC 223 instrument can be connected with an impulse measurement device (DiAS, HiAS or DMI) to form an integral impulse control and measurement system. The GC 223 can also be fully remote controlled via RS 232 interface by a computer to integrate the system into a complete manufacturing chain. The GC 223 system supports manual operation as well as automated test sequences. The software menu is especially designed for intuitive, fast and safe user interrogations. It is equipped with a 5.2’’ liquid crystal display and a numerical keypad. The basic version of the GC 223 includes all necessary functions to control an impulse system. The instrument can be upgraded with programmable test sequences and a remote control software. The GC 223 is primarily intended for use in automated test bays which are controlled by a host computer. Beside this the instrument can also be applied for stand alone impulse generators which do not require an embedded solution. Beside the control module GC 223 Haefely also offers a more sophisticated impulse generator control system GC 257. Control unit for operating an impulse generator. It provides control for the charging and triggering process of an impulse generator. Charging Control Unit suppresses interferences and minimizes wiring by collecting all control and data lines from the generator into two main cables. Integration of measuring device and adaptation of its measuring values for efficiency calculations. Chopping gap control allows all necessary adjustments for chopping lightning or switching impulses Large graphic display and buttons marked with clear symbols simplifies operation and supports quick and easy access to all functions and parameters. Safety features are implemented in hardware independent of any software. Additional switches, lamps and horns can be placed in optimal positions. Optional: Programmable test sequences optimized for automated production testing. Remote control software to operate the unit from a computer. BENEFITS Easy and safe reduce the learning curve and minimizes any dangerous situations. Rugged and compact guarantee high durability and helps reducing the installation costs. Versatile and compatible support easy integrating into a manufacturing chain. Lowest cycle time ensures that even the highest factory throughput can be accomplished.

SYSTEM DESCRIPTION CHARGING PROCEDURE To charge an impulse generator it is necessary to divide the charging process into two sections. DUT Charging Control Unit CCU 104 Control Module GC 223 During the first section the impulse generator is charged by applying a steep voltage ramp. As a result a current of up to 90 A (CCU 104) resp. 200 A (CCU 105) flows into the generator. After the impulse generator is loaded with 95% of the charging voltage the steepness of the voltage ramp is decreased as illustrated in the graph below. This is necessary because the charges are not uniquely distributed...

HIGH VOLTAGE TEST CONTROL MENU The control menu of the GC 223 takes care of adjustments used to perform daily tests with the impulse generator. Following parameters can be edited: ■ Charging voltage: per stage, in total or, if an additional measurement device is installed, the actual voltage at ■ Polarity: positive or negative with clear display of the polarity change ■ Charging time: minimal or user-defined ■ Trigger mode: manual, automatic or external ■ Counter: number of impulses and number of flash- overs when using an external measurement device ■ History: information on previous...
