GDUI-511PD Acoustic PD Camera
GDUI-511PD Acoustic PD Camera, using high sensitivity digital microphone array, is mainly used to detect the leakage of pressurized gas and partial discharge of electrical insulation equipment, and can be extended to detect infrared thermal imaging, internal leakage or other detection functions.
It features built-in flash lights for low-light detection and supports external sensor integration. The aluminum alloy casing enhances durability, while the explosion-proof design meets structural and circuit requirements. Some models are certified for explosion-proof environments (ensure your purchase is explosion-proof certified).

GDYT-10kW PD-free Induced Voltage Test System
GDYT-10kW PD free induced voltage test set is variable frequency AC power supply (hereinafter called VF power supply). It inputs single AC voltage and frequency, after inversion, it generates stable and pure sine wave.
The equipment uses PWM (Pulse Width Modulation) technology to make the device small size, light weight and highly efficient. Digital signal processing technology provides high-precision and high-speed measurement functions such as voltage, frequency, current, apparent power, and power factor. Meanwhile, it use high-power IGBT module design to reduce circuit complexity, improve product stability, reduce power consumption, and increase the capacity of a single unit, plus a number of ultra-isolation transformers to completely isolate the mains and the load to increase the functions, which can ensure the accuracy.

GDPD-PTU PD Online Monitoring System for Oil Transformer
The aging and damage of the internal insulation of the transformer mostly starts from local discharge. The reason for local discharge is that the electric field is too concentrated at a certain point, or the electric field strength at a certain point is too large. At present, the main methods for detecting transformer local discharge faults are: UHF ultra-high frequency monitoring method, HFCT high-frequency pulse current local discharge measurement method (pulse current method), ultrasonic local discharge measurement method (ultrasonic method), and oil gas chromatography analysis method.
