Automatic HV Control Unit

This control Unit is designed for fully-automatic control of high voltage test systems.

Following application areas can be served:

• fixed-frequency AC test transformer system
• variable-frequency AC resonant test system

• Ease of use
• High flexibility because of the different working modes
• User specific test protocols
• Multiplicity of test procedures
• Safetyfor the test object
• Upgrade of already existing test systems

General Features:

• Control of master and the operating contactors
• secondary Over-voltage and primary over-current control with built-in high-speed circuit breaker
• Activation of limit switches of the regulating transformer with ZERO-START interlock function
• Connection for external safety interlock
• Control of an automatic groundingunit
• Push-button switches for "High Voltage" ON/OFF
• EMERGENCY STOP switch
• Supply voltage: 115 V or 230 V, 50/60 Hz (please select)
• Dimensions: 19" rack mount version, 4 HU

The control system has four different, independent working modes (partly optional features). This allows a very flexible use of this Control Unit.

1. Manual Mode

• Operation via built-in touch-screen
• Values like current and voltage of the test circuit or of the power supply as well as graphic curves are displayed on the 8.4"-TFT-Display
• Pre-selection of voltage and frequency (frequency only at variable-frequency AC resonant test systems)
• Calibration of all relevant values

2. Automatic Mode

• see 1. manual mode
• Selection of user-defined programs (ramp with one voltage level can be varied)

3. Remote control mode - Software (optional, not included)

• Complete remote-control via PC and special host-program ("Easy Remote Control") for Microsoft Windows operating systems
• Connection via Ethernet interface
• Graphical representation of the actual measured values
• Start and Stop of the programmed voltage ramps respectively test procedures
• Unlimited entering of more test procedures´
• Test procedures can be stored on hard disk
• Measured values and graphics can be stored as file on the hard disk of the Control-PC

Optional to 3. (not included):

• simultaneous control of LDIC PD measuring system LDS-6 incl. data acquisition of the PD level, e.g. for automatic "GO" or "No GO" decision at routine tests
• simultaneous control of LDIC tan delta measuring system TD-SMART incl. data acquisition of the tan delta
• on customers request, an user-specific test protocol can be printed out after finishing the test

4. Remote control mode - Hardware (optional, not included)

• according to customer-specific inquiry controlling of external devices (e.g. robotics)

• Dissipation and capacitance measuring system TD SMART
• PDMeasuring SystemPD SMART
