Applications

Applications for Safety, Routine Testing, System Integration, and PD Tests

Safety Tests

In applied AC high voltage testing, electrical devices are exposed to controlled high voltage conditions to assess their performance, durability and safety. It assesses the integrity of the insulation, detects defects and ensures compliance with safety standards. This test is crucial for checking the reliability of electrical systems in industry and power distribution.


Partial Discharge Tests

The GHV3000 is an essential tool for partial discharge (PD) testing, known for its precision in voltage adjustment and high accuracy, which are critical for obtaining reliable results. One of its key features is the ramp function, which enables a controlled increase in voltage over time. This feature is particularly valuable as it facilitates accurate detection and analysis of partial discharges by allowing testers to monitor the PD activity under gradually increasing voltage conditions, thereby ensuring a thorough and precise evaluation of insulation performance and system reliability.


Transformers, Chokes

The GHV3000 is a high-precision instrument for transformer and choke testing, offering accurate voltage control crucial for reliable diagnostics.

Its ramp function allows for a gradual increase in voltage, aiding in the thorough detection and analysis of performance and potential faults.

Motors, Switchgear

The GHV3000 is an advanced test device for motor and switchgear, offering precise voltage control and high accuracy essential for thorough diagnostics. Its ramp function allows a controlled increase in voltage, facilitating the detection and analysis of potential faults. This ensures a comprehensive evaluation of the performance and reliability.

Cable Systems

The AC high voltage test for cables evaluates insulation integrity and electrical performance. By subjecting cables and accessories to controlled overvoltages, technicians assess their resilience against normal operations and potential faults. This test identifies defects such as insulation breakdown or partial discharges, ensuring compliance with safety standards and operational needs. Crucial for power transmission, distribution networks, and industrial applications, it ensures the reliability and longevity of cable systems.

Semiconductors

The AC high voltage test for semiconductors evaluates the performance of insulating sections under electrical stress. It verifies device reliability and compliance with safety standards critical to power electronics and semiconductor manufacturing.
