JKJQ‑1A Insulating Oil Dielectric Strength Tester

Part Number: JKJQ‑1A

The JKJQ‑1A is a fully automatic, portable single-cup tester designed to measure the dielectric (breakdown) strength of insulating oils used in transformers, switchgear, and high-voltage equipment. It complies with standards GB/T 507‑2002, DL429.9‑91, and DL/T 846.7‑2004, and uses a microprocessor to automate the test cycle—voltage ramping, holding, stirring, breakdown detection, discharge, analysis, memory storage of up to 100 readings, and thermal printout—ensuring accurate, repeatable results with reduced operator effort and portable convenience.

                                                
                                                    Automatic, High-Precision Breakdown Testing                                                
                                            
                                                Features a microprocessor-controlled voltage ramp up to 80–100 kV (optional), with distortion under 3% and accuracy of ±3%, ensuring consistent, standard-compliant BDV testing.

                                                
                                                    Fully Automated Workflow                                                
                                            
                                                Executes the entire test cycle—ramp, hold, stirring, rest, discharge, calculation, printing, and memory storage—without manual intervention, improving lab efficiency and safety.

                                                
                                                    Intuitive Touchscreen & Multilingual Display
