Chroma Systems Solutions, world leading provider of electrical power test equipment and systems, is pleased to announce the release of their new 19055 Series of Hipot Analyzers. Chroma’s 19055-C not only includes AC/DC hipot and Insulation Resistance (IR) tests but also adds a new measurement technology; Corona Discharge Detection (CDD). In Discharge Level Analysis (DLA) mode the user can specify the, Corona Discharge Start Voltage (CSV), Flashover Start Voltage (FSV), and Breakdown Voltage (BDV).
Applications that benefit include electric motors, transformers, capacitors, photocouplers and insulation materials. The Discharge Level Analysis function in Chroma’s 19055-C provides valuable data to verify component insulation and insulation materials. Discharge in electrical components such as motors, transformers and capacitors gradually damage the insulation or adjacent components inside these devices, leading to premature product failure. For example, Corona discharge is typically an early symptom of an impending breakdown. In electric motors, corona detection can be used for turn-to-turn or turn-to-ground tests to avoid insulation failure from corona discharge. DLA mode will indicate and report the withstanding voltage dependent on the limit levels of corona, flashover and breakdown allowing for improvements to insulation thereby increasing the quality of the product.
AC/DC hipot and Insulation Resistance can be programmed in AC 5kV/100mA with a 500VA output rating and complies with EN50191 requirements. For contact checking during the hipot test, the 19055 series is equipped a new High Frequency Contact Check (HFCC) function as well as their patented Open Short Check (OSC) function increasing test reliability and efficiency significantly. For ease of operation, the 19055 series is equipped with a large LCD screen. In addition, the GFI human protection circuit and Floating safety output prevents electrical hazard to the operator.
The 19055-C Hipot Analyzer with Corona Discharge Detection is added to a long list of hipot and safety test equipment manufactured by Chroma. They are dedicated to providing the highest quality equipment for compliance and R&D test engineers as well as unparalleled service and support.
