JKJQ‑3 Dielectric Strength Tester

Part Number: JKJQ‑3

The JKJQ‑3 is a fully automatic single-cup dielectric breakdown tester designed for testing transformer, capacitor, and insulating oils. Using microprocessor control, it automates the entire test cycle—voltage ramp‑up (up to 80 kV standard), hold, stirring, breakdown detection, discharge, calculation, printing, and data storage—delivering consistent and accurate results with minimal user interaction. Built for both field and laboratory use to ensure oil quality, safety, and compliance with national testing standards.

                                                
                                                    Microprocessor-Controlled Full Automation                                                
                                            
                                                Automates the entire dielectric test cycle—including voltage ramp‑up, hold, stirring, breakdown detection, and discharge—for reliable and repeatable performance.

                                                
                                                     High Precision with Auto Recording                                                
                                            
                                                Powers samples to as high as 80 kV (standard), with low distortion and integrated data storage—keeping up to 100 results for reporting and traceability.

                                                
                                                    Operator Safety & Ease of Use                                                
                                            
                                                Features built-in protections for over‑voltage, over‑current, electrode limit detection, plus automatic discharge and simplified controls via an LCD interface—enhancing safety during high-voltage tests.
