Reference Standard: DL / T848.4-2004 Introduction DBYD series power frequency voltage test equipment (control box / unit + test transformer) is test equipment nanny Hubei Electric Power According to the latest industry test standards and design, with a professional style Standard insulation chassis, its safe, reliable, powerful, easy to use, easy maintenance, is mainly used for all kinds of electrical products, electrical components, insulation materials insulation strength test specified voltages to assess the level of insulation products, found to be insulation defects test, the ability to measure over-voltage electricity to run the relevant departments, electrical appliances manufacturing, metallurgy, coal, electric railway departments, research institutes and universities that require voltage test equipment of choice. Features monitoring functions:? High Voltage Low power indicator indicates the zero current work indicates that the timing instructions Protection:? Overcurrent protection, zero start protection, sound and light alarm to remind the language using the new time relay, timer broader (1S ~? 99H)? using the new current relay, more accurate, more reliable, and to ensure personal safety equipment. ? Test transformer high voltage coil is cylindrical multi-tower, made of high quality polyester enameled value and high-voltage insulation material around the system. ? Test transformer is equipped with a movable iron wheel. Light weight, small size, easy to move, superior performance characteristics.
