The hipot test is one of the major test items in electrical safety testing. All electrical components and products including transformers, capacitors, power supplies, chargers, and home appliances require hipot testing. With more than 3 decades of experience in developing instruments for test and measurement, Chroma created the 19020 Multi-Channel Hipot Tester with a brand new architecture. It can measure the hipot leakage current of all channels at the same time and conduct tests on up to 100 DUTs simultaneously. Chroma 19020 saves space on the production line by eliminating the need to purchase multiple hipot testers. Its one-time multi-channel test increases the efficiency of electrical safety testing. It improves manufacturing efficiency and reduces testing risks for products that require only hipot testing. Chroma 19020 also has powerful functions for Flashover detection and Open/Short Check. With several international patents, it is the best tool for regulatory electrical hipot tests as it not only offers reliable quality, but also creates a highly efficient test platform.

The Chroma 19055 Series Hipot Analyzer is designed for Hipot test and analysis. It has a maximum output power of 500VA, a maximum AC output of 5kV/100mA, and Floating output for EN50191 requirements. (Please refer to the application notes for more detail information.)

The 19055-C includes ACW/DCW/IR tests, but also has a new measurement technology; Corona Discharge Detect ion (CDD). In addition, the Breakdown Voltage (BDV) Analysis can detect faults as follows;

• Corona discharge Start Voltage (CSV)
• Flashover Start Voltage (FSV)
• Breakdown Voltage (BDV)

The Chroma 19055 series also has both High Frequency Contact Check (HFCC) and Open Short Check (OSC) functionality. This increases the test reliability and efficiency significantly through application of the contact check during the Hipot test.

The Chroma 19055 series is equipped with a large LCD screen which is convenient for the user to operate and judge. In addition, a GFI human protection circuit and Floating output design prevents exposing users to electrical hazards.

Key Features

Chroma 19056/19057 Hipot Analyzer is an equipment specially designed for testing and analyzing ultra-high withstand voltage. The series of models include 10kVac/12kVdc/20kVdc with maximum AC20mA/DC10mA output can perform AC/DC withstand voltage and insulation resistance tests with contact check during production line test. In addition to the patented OSC (Open Short Check), High Voltage Contact Check is added to test the components with high insulation capability when high voltage outputs to improve the testing reliability and efficiency.

Chroma 19056/19057 with GFI (Ground Fault Interrupt) is designed to protect operator's safety when abnormal ground current (A2-A1) occurs.

The Hipot Analyzer provides high withstand voltage test and analysis for optical couplers, HV relays, HV switches and PV modules, which have better insulation capability.

Charge and discharge are required for capacitive components when doing DC withstand voltage test. The Hipot Analyzers have fast charge function that can increase the production test efficiency .

The Hipot Analyzer of entire series has Flashover (ARC) detection function. Through the start voltage, end voltage, no. of steps and time, it can perform discharge level analysis. Phase judgment is provided in DLA (Discharge Level Analysis) mode to set inspection for Flashover (ARC) and Breakdown test (high limit). When a defect appears in the test, the 19056/19057 will show the withstanding voltage to indicate the Flashover Start Voltage (FSV) or BreakDown Voltage (BDV) respectively. In addition, External Oscilloscopes can be mounted to check the waveform at the same time during analysis. The R&D engineers can perform product analysis and study utilizing the test results to improve the weakness of insulation components.
