Exploring Guardian Hipot Analyzer

Guardian Hipot Analyzer

Chroma 19056/19057

Provides high withstand voltage test and analysis for optical couplers, HV relays, HV switches, and PV modules components, which have better insulation capability

Hipot Test: Output Voltage

AC: 0.1~10kV (19056)
DC: 0.1~20kV (19057)

Hipot Test: Cutoff Current

AC: 20mA (19056)
DC: 10mA (19057)

Insulation Resistance Test

0.1MΩ~50GΩ / 5kV max

Chroma’s Guardian 19056/19057 Hipot Analyzer is specially designed for testing and analyzing ultra-high withstand voltage. The series of models include 10kVac / 12kVdc / 20kVdc with maximum AC20mA / DC10mA output that 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.

Ground Fault Interrupt (GFI)

The Guardian 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 testing 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 functionality that can increase production test efficiency.

Flashover (ARC) Detection

The entire series has Flashover (ARC) detection functionality. They can perform discharge level analysis through the start voltage, end voltage, number of steps and time. 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.
