Description

Electrical safety testing is a major item in electrical product quality testing. All electrical products like adapters, SMPS, charges, house appliances, information technology products, and video products are required to undergo electrical safety testing.

The 19032 series combines Hipot, Insulation Resistance (IR), Ground Bond (GB), Leakage Current (LC)/AC LC/DC LC and Dynamic Function Tests. Space savings can be up to 50% of production line space, through not purchasing multiple safety test instruments. The 19032 is able to increase the efficiency of electrical safety testing during manufacturing and reduce associated labor costs.

19032 Hipot Tester

Open/Short Check (OSC)

Patent No. 254135
All manufacturers have to solve the problems of error connections and unconnected test cables with their production line testers. Chroma’s 19032 is equipped with an open/short check function (OSC) for product testing. This eliminates the potential for false failures.

 

Flashover Detection

The Guardian 19032 has the same Flashover Detection as many other Chroma safety test instruments. Flashover is electricity transient or non-sequential discharge on the inner surface of the insulation component which cause the DUTs original insulation to lose effectiveness, create a carbonized electrically conductive path to be generated, and damage the product. Flashover can’t be detected by leakage current, test voltage or shift rate of leakage current is required. Thus, Flashover Detection is one of inevitable inspection item in HV test.

Power Supplies, Adapter & Charger Safety Testing

Safety Analyzer Power SupplyPower supplies in electronic products, including SMPS, adapters, and chargers, need to tested for electrical safety. According to various power design methods and test conditions, the 19032 offers programmable edit and solution, allowing the operator to complete all test at one time.

A number of power product designs must have the insulation capability of the input terminal (Primary) to output terminal (Secondary) that is sufficient to protect against damage inside the component. Thus, the output terminal or Floating needs to be Hipot tested. The 19032 provides an isolation test point with high voltage which allow you not to change the fixture or cable manually, and perform the P-S Hipot test directly after the P-G Hipot test.

If there is danger in making contact with the output terminal (Secondary), the dynamic leakage current test also needs to be performed.

Measurement Technology

Open/Short Check (OSC) (Patent 254135)

OSC function is used to check the connection is open (bad contact) or short (DUT short) during the test procedure. When open occurred during test procedure, no good product will be judged as good product. When short occurred during test procedure, screening earlier to reduce the damage on equipment for saving test cost.

Generally speaking, the DUT has capacitive load (Cx) from tens to thousands pF under normal status. To form a micro capacitance on open circuit interface once connection is interrupted (as Cc in figure 2). Generally speaking, the capacitance is lower than 10pF thus total capacitance is far lower than the status of normal product. The capacitance is far higher than normal status when DUT short or close to short. Therefore, users judge the short problem by using high/low limit value of capacitance change.

Whatever the operator touches any Hipot test terminal under Floating status. The earth leakage current is lower than 3.5mA, the operator won’t be hurt by electricity.

 

Support Dynamic Leakage Current Test

The current brimmed after flow through insulation resistance, we called it as Leakage Current. When the leakage current contact with human body, the current flows to Earth via human body thus causes electric damage. The leakage current is testing under operating status. A human body RC network will be added in leakage current test, it can simulate the value of leakage current in real condition.

The leakage current has different test modes and standards in accordance with different safeties and test points. The most often seen current tests
are Earth Leakage Current, Patient Leakage Current and Patient Slave Leakage Current.

The Guardian 19032 is used with different dynamic leakage current module and human body simulation equivalent circuit for the requirements of various safety modules. It can apply to Electrical Safety Testing of House Appliance, Video Product, Medical Equipment and etc.
