The insulation performance of power equipment, electrical circuits, and new energy equipment is the core key to ensuring the safe and stable operation of the power system and preventing safety accidents such as leakage, short circuit, and electric shock. In the fields of power grid operation and maintenance, photovoltaic wind power new energy, industrial electrical, building electromechanical, rail transit, etc., long-term operation of equipment is prone to insulation aging, moisture, damage, fouling and other problems. If not detected and investigated in a timely manner, it is extremely easy to cause equipment failures, power outages and even safety hazards. Traditional insulation resistance testers have problems such as large range limitations, unstable readings, cumbersome operation, weak anti-interference ability, and poor portability, making it difficult to adapt to complex outdoor working conditions, high-altitude operations, and batch testing needs. To meet the high-precision, high-efficiency, and highly portable requirements of electrical insulation safety testing in various industries, Jiangsu Jingwei relies on mature electrical testing technology and has ingeniously developed the JW-J25 insulation resistance tester. With the core advantages of wide range, high precision, strong anti-interference, easy operation, and high safety, it creates a comprehensive electrical insulation testing solution to safeguard the safe operation of various power and electrical equipment.
