No part of this publication may be reproduced, transmitted, stored, or translated in hardcopy or electronic form without the written consent of HV Diagnostics Inc, USA. NOTE: The information presented in this instruction Manual is believed to be accurate and correct for the intended use of this product. Should this instrument be used for other applications and purposes not covered herein, please contact HV Diagnostics Inc to validate its suitability. This Manual , all of its contents and the instruments specifications are subject to change without notice. Operating Manual HVA60 3 Ver. 01/2005. Warranty Terms HV Diagnostics Inc provides a one-year warranty from the original purchase date of instrument for all necessary parts and labor.

2 This warranty and our liability is limited to replacing or repairing, at our discretion, the defective equipment. Equipment that is returned to our company must be suitably packed and all shipped items must be prepaid and insured. This warranty does not include normal consumable items like lamps, paper rolls, printer ribbons, batteries or other expendable items. No other warranties are expressed or implied. This warranty will be voided in the event of abuse, incorrect operation and use, unauthorized modification or repairs or failure to perform the specified maintenance as indicated in this operation Manual . Operating Manual HVA60 4 Ver. 01/2005. Safety Precautions and Prerequisites All equipment to be high potential tested must be de-energized and properly isolated from all power sources. All equipment grounds must remain in place. All high potential test equipment cable connections must be clean and secure. Separate equipment ground connections should be used.

3 Ground integrity must be maintained at all times. Avoid testing alone always have someone available who is able to render first aid and resuscitation if required. Do not install substitute parts or make unauthorized modifications to the test instrument or its accessories as this may introduce additional risks and unknown hazards. To ensure that all safety features in the instrument are maintained, it is strongly recommended that all repairs and modifications be performed by HV. Diagnostics Inc or one of their authorized repair service centers. Before using this test instrument, please read through the Operating Manual in its entirety. Make sure you clarify any points that you feel unsure or uncertain about before using the instrument. Make sure you are knowledgeable about the proper application, safety, potential hazards involved, and procedures in using the test instrument. The awareness for safety, an integral part of the job, cannot be over emphasized.

4 Safety is the responsibility of the user/operator. All personnel Operating the high potential test equipment must wear high voltage gloves. Verify the class rating/voltage of all protective devices ( rubber blankets) to ensure proper protection. Use suitable barriers, barricades, or warnings to keep persons not directly involved with the work away from test activities. Personnel must be notified to prevent other workers, as well as the general public, from entering the high potential test area. Vacuum bottles must only be high potential tested with AC. Dangerous X-rays can be produced when vacuum bottles are high potential tested above their rating with DC. Since some electrical apparatus such as cables are essentially capacitors, they can hold a charge after being exposed to a high potential test. These electrical apparatus must therefore remain grounded for sufficient time to drain off any remaining charge. Never assume that a piece of equipment that has been high potential tested is safe to handle without using the necessary safety equipment and grounding procedures.

5 Always treat exposed connectors and conductors as potential electric shock hazards. All auxiliary electrical apparatus such as switchgear, surge arresters etc must be isolated from the test source and device under test (DUT). The test leads must always be disconnected from the device under test (DUT) before attempting to disconnect from the test equipment. The ground connections must be the first made and the last removed. Any interruption of the grounding connection may create an electric shock hazard. Operating Manual HVA60 5 Ver. 01/2005.

Introduction: The model HVA is an easy to use, single piece, microprocessor based, field portable, fully automatic DC and VLF ( very Low frequency ) high voltage test instrument developed for the high potential testing of the insulation dielectrics of various types of electrical apparatus. 2. Application: The HVA test instrument is designed to perform high voltage insulation testing of various types of electrical apparatus. These applications include, but are not limited to, those testing requirements involving highly capacitive loads such as cables and generators. Other testing applications include switchgear, transformers, rotating machines, insulators, bushings etc. In cable testing applications, the HVA is capable of testing both extruded (such as XLPE) and laminated cables (such as PILC). In addition, the HVA can be used for testing both the cables main insulation section as well as the cable's jacket/sheath.

7 Both DC (positive and negative with respect to ground) and AC VLF. Sinewave and Squarewave outputs are included as standard. Test sequences according to the relevant test standards can be automatically or manually implemented. This flexibility allows the instrument to be used on a multitude of different applications requiring either high voltage AC or DC. The instrument also has a sophisticated Arc management control system allowing users to select various tripping or fault condition modes. The instrument measures and records the capacitance, resistance, dielectric breakdown voltage, RMS current and applied voltage of the device under test. Operating Manual HVA60 7 Ver. 01/2005. 3. Special Features: Optimized frequency Selection: The HVA has the ability to optimize the frequency when testing capacitive loads. Its does this automatically and without having to restart the instrument. Fully Automatic Test Sequences: The HVA can be easily programmed to follow a particular test sequence, applying user defined test voltages, durations, and waveforms.

8 Easy to use Menu Guided, single pushbutton operation. True Symmetrical Sinusoidal and Squarewave outputs waveforms that are load independent within the specified load range of the equipment. Built in Memory allows the storing of automatic test sequences and test reports to allow reviewing or downloading of test results to a Windows compatible PC. Short Circuit protected with active arc management regulation to avoid the usual nuisance tripping of other conventional HV test equipment. Both Negative and Positive DC Outputs and Variable frequency VLF outputs in both Sinewave and Squarewave. Real Time Output Voltage Display. The actual instantaneous output voltage is displayed on the test instrument LCD display. Automatic load measurement without having to make several connections to the device to be tested before high voltage testing can commence. No mechanical moving parts or oil is used in the generation or insulation of the high voltage inside the instrument.

9 This minimizes maintenance and improved durability and reliability of the test instrument. Operating Manual HVA60 8 Ver. 01/2005. 4. Safety Features: Short Circuit and Transient protected. Status Display of all important safety interlocks and functions. Safe easy-to-use operation with Local Emergency Off Switch with key lockout facility. Remote Emergency Off Interlock: For connection to a foot switch or gate switch or another remote Emergency off pushbutton for example. This interlock also provides a switch facility to connect to a green (HV Off) or red (HV ON) remote external lights (not provided). Fully integrated discharge and transient circuit to safely ground the DUT after testing and protect the unit from transient over voltages respectively. Zero start interlock. Initial load clearance test at reduced voltages to check if any shorts or grounds are present before high voltage testing commences. Operating Manual HVA60 9 Ver. 01/2005.
