CAL1, CAL2, and CAL3 Calibration Impulse Generators

<p>Partial discharge measurement is a useful tool to analyse the insulation of high voltage components. However, partial discharges can usually not be measured directly, just the apparent charge of such signals are captured by the measuring instrument. Therefore, a calibration of the whole measuring system is required. To do this, short-duration current pulses of a known charge magnitude are injected into the system, and from this, a scale factor can be calculated for later partial discharge (PD) measurements.</p> <p>Power Diagnostix offers a broad range of calibration charge injectors suitable for the calibration of PD measurements. The appropriate choice of a calibrator depends on the range of typical charge values of the PDs being measured. PDIX calibrators are suitable for calibrating test setups for the following assets:</p> <p>Additionally, the calibrators of the CAL1 series can also be used for time domain reflectometry in cables to determine the cable length and the location of joints.</p> <p>The instruments of the CAL series can be equipped with optional features to suit a broad range of applications. Available options are:</p> <p>Every PDIX calibrator comes with a set of clamps, plugs, adapters, and pre-assembled cables for the comfortable connection of the calibration impulse generator to the measurement setup. The ready-to-use sets include everything for a quick and convenient connection of the device to the specific test setup.</p> <h3>Key features</h3><ul><li>Transformers</li><li>Rotating machines</li><li>Gas-insulated switchgear</li><li>Suitable for 50 and 60 Hz, switchable</li><li>Double pulse with adjustable time delay (for CAL1 series)</li><li>Remote power input for the supply by an external 12 to 24 V DC voltage</li><li>Selection switch for single pulse or continuous pulses (allows the output of manually triggered single pulses)</li></ul>
