Intelligent Automatic Touch Screen Control Oxygen Index Meter
Shanghai Dean Electrical Co., Ltd
1. Full-color touch screen control. You only need to set the oxygen concentration value on the touch screen, and the program will automatically adjust to the oxygen concentration balance and sound prompt.2. The step proportional valve is adopted to greatly improve the accuracy of flow control, and the closed-loop control is adopted to automatically adjust the oxygen concentration drift program back to the target value during the test, which avoids the disadvantage that the traditional oxygen index tester cannot adjust the oxygen concentration during the test and greatly improves the test accuracy.

PDIV Tester for EV Motor
PDIV 500-T
Shanghai Dean Electrical Co., Ltd
Differing from partial discharge with high frequency pulse which produce sound and light phenomenon, the power frequency AC voltage reaches a certain threshold, can only produce instantaneous current leakage around the tested sample, it can be detected through discharge capacity (unit: PC) to evaluate partial discharge phenomena..The instrument PDIV 500-T is designed to put samples such as enameled wire, insulation paper/film, and electric motor stator in the High temperature / humidity environment chamber, applying a power frequency voltage with a programed rising speed, and prefect ground connection must be guaranteed , through the coupling capacitor as the medium, the continuous detection of discharge capacity against the voltages will create formulation between the Voltages and discharge capacities (pc), the software will find the discharge voltage threshold called PDIV.
