Although It Is A Trustworthy Withstand Voltage Tester, It May Also Pose A Certain Risk To The Operator During Operation Due To Problems Such As The Operator Itself Or External Influences. Therefore, Whether It Is A Professional Manufacturer Of Withstand Voltage Testers, Related Companies That Still Use Withstand Voltage Testers Should Try Their Best To Prevent Such Risks From Occurring, So How To Reduce Such Potential Risks?
Generally Speaking, Many Mid-To-High-End Withstand Voltage Testers Are Designed With An Embedded Intelligent Anti-High Voltage Electric Shock System. This System Is Also Called Smart GFI For Short. It Can Detect According To The Current Model’s Application, Assuming An Electric Shock Occurs. , Leakage And Other Problems Is That A Qualified Withstand Voltage Tester Will Actively Block The High Voltage Output Within One Millisecond To Ensure The Safety Of The Operator. Therefore, In The Case Of Equal Operation, A Qualified Withstand Voltage Tester, As Long As The Operator Does Not Make Too Many Mistakes, There Will Be Little Risk Of Electric Shock For The Operator.
In Order To Protect Customers And Operators, Manufacturers That Professionally Produce Withstand Voltage Testers Need To Complete Several Types Of Safety Inspections When They Complete The Production Of The Equipment Introduced By Yang To Ensure That The Products Comply With Industrial Standards Regarding Product Structure, Function, And Process Standards.
It Includes Withstand Voltage Inspection, Insulation Inspection, Etc. It Is Best For The Manufacturer To Carry Out Related Inspections Before The Parts And Equipment. The First Thing Is To Prevent Unqualified Components From Being Installed Into The Product, Which Poses A Potential Risk. For Now, For A Qualified Manufacturer, Its Production, Inspection And Other Processes Must Be Strictly In Accordance With ISO International Standards, And The Final Products Must Also Reach The ISO International Certification Standards, Which Means That Everything From Parts To Products Must Reach The International ISO. Only In This Way Can The Certified Quality Standards Be Adjusted To Eliminate Potential Risks. Of Course, Companies That Use Related Equipment Must Organize Operators On Time To Conduct Drills. Newcomers Must Operate Under The Supervision Of Experienced And Experienced Employees, So As To Thoroughly Prevent Risks Due To Operating Errors.
What Are The Benefits Of AC Withstand Voltage Inspection?
Generally, The AC Withstand Voltage Tester Is Easier To Obtain The Acceptance Of Safety Organizations Than The DC Withstand Voltage Tester. The Primary Reason Is That Most Of The Tested Items Will Be Operated Under AC Voltage, And The AC Withstand Voltage Inspection Provides The Benefits Of Two Polarity Replacement To Apply Pressure To The Insulation, Which Is Closer To The Pressure That The Product Will Encounter In Practical Use. Since The AC Inspection Will Not Charge The Capacitive Load, The Current Reading Remains Consistent From The Beginning Of The Voltage Application To The Completion Of The Inspection. Therefore, Since There Is No Stabilization Problem Required To Monitor Current Readings, There Is No Need To Gradually Increase The Voltage. This Means That Unless The Product Under Test Senses A Sudden Applied Voltage, The Operator Can Immediately Apply The Full Voltage And Read The Current Without Waiting. Since The AC Voltage Will Not Charge The Load, There Is No Need To Discharge The Device Under Test After The Inspection.
What Are The Disadvantages Of AC Withstand Voltage Tester?
When Checking The Capacitive Load, The Total Current Is Composed Of Reactive Current And Leakage Current. When The Reactive Current Is Much Greater Than The True Leakage Current, It May Be Difficult To Detect Products With Excessive Leakage Current. When Inspecting Large Capacitive Loads, The Total Current Required Is Much Greater Than The Leakage Current Itself. As The Operator Faces A Greater Current, This May Be A Greater Risk.
What Are The Benefits Of DC Withstand Test?
When The Device Under Test (DUT) Is Fully Charged, Only Real Leakage Current Flows Through It. This Enables The DC Withstand Voltage Tester To Clearly Show The True Leakage Current Of The Product Under Test. Since The Charging Current Is Short, The Power Requirement Of The DC Withstand Voltage Checker Can Generally Be Much Smaller Than The Power Requirement Of The AC Withstand Voltage Checker Used To Check The Same Product.
What Are The Disadvantages Of The DC Withstand Voltage Tester?
Since The DC Withstand Voltage Test Does Charge The DLT, In Order To Eliminate The Risk Of Electric Shock For The Operator Who Handles The DLT After The Withstand Voltage Test, The DLT Must Be Discharged After The Test . The DC Check Will Charge The Capacitor. Assuming That The DUT Uses AC Power In Practice, The DC Method Does Not Imitate The Actual Situation.
