The Cylinder Type HV AC Test Transformers are specifically designed for test applications which require a stable output voltage, even if the load may change during testing. For example for heavy corona, wet tests or pollution tests to name a few. These systems are also especially useful for when the load is inductive, such as inductive voltage transformers. Depending on our customer’s specific needs, it’s possible to stack several transformers – allowing us to reach very high voltages while also taking up very little valuable floor space

• Flexible high voltage connection options
• Compact dimensions perfect for minimum space requirements
• Sophisticated protection features for optimal test object and personnel protection
• Large range of applications
• Low acoustic noise level (ca. 65 – 75 dBA)
• Power compensation inductance guarantees linear voltage distribution for systems with 3 or more stacked transformers and reduces the power required on the primary (LV) side of the test system
• Option to add air-cushion base frame

1. This series of insulated cylindrical high-voltage test transformers adopts a single frame iron core structure. The primary winding is wound around the iron core, and the high-voltage winding is outside. This coaxial arrangement effectively reduces magnetic leakage, thereby increasing the coupling between windings.
2. Voltage, current, time, status information, and prompt information are displayed on a 10 inch large LCD screen, with clear and intuitive readings;
3. Simple and clear operation, suitable for various application scenarios;
4. Touch based operation, all functions can be preset in advance, improving the safety and reliability of the product;
5. Status reminder function;
6. Alarm function, closing alarm, 5-second buzzing alarm prompt; Abnormal voltage signal collection and buzzing alarm;
7. Emergency stop function, during automatic control, this function can achieve an emergency stop for boosting or lowering pressure at any point;
8. Automatic timing function. When in automatic control, when the voltage automatically rises to the set value, the equipment automatically starts timing. When the timing time is up, the equipment automatically reduces voltage and returns to zero position;
9. Manual control mode, which is similar to the traditional electric lifting/lowering method. The lifting/lowering is controlled by touch keys, and the equipment automatically determines the upper/lower limit positions. High voltage overvoltage and low voltage current protection, high voltage overcurrent protection;
10. Adopting a combination of hardware and software anti-interference technology, it has stable performance and strong anti-interference ability.
