Profile:

The KDZD3088 combines precision ultrasonic sensing, real-time data transmission, and ergonomic design to revolutionize power line巡检 (patrol). It captures ultrasonic signals at 40 kHz, filters noise, and delivers actionable insights via a color touchscreen or connected smartphone. With cloud connectivity, GPS positioning, and long battery life, it supports both handheld and low-speed vehicle-based inspections—making it one of China’s most effective ultrasonic PD diagnostic tools for modern smart grid maintenance.

Features:

High Sensitivity: Detects discharges ≥100 pC at distances up to 51 m (110 kV)
Real-Time Cloud Sync: Stream data to mobile devices and cloud platforms for remote analysis
Multi-Mode Display: Real-time, instantaneous, and peak-hold modes for flexible diagnosis
GPS & Environmental Logging: Built-in GPS (50-channel), temperature (–40~120°C), and humidity (0–100% RH) sensors
Audio & Data Recording: Saves WAV audio (48 kHz) and DAT measurement files; up to 160,000 records on 16 GB USB
Long Battery Life: 8–20 hours runtime (depending on mode); 8000 mAh Li-ion battery
Ergonomic & Lightweight: Only 0.6 kg, with 3.5" touch screen and noise-canceling headphones
Vehicle-Ready: Supports low-speed mobile patrol with optional active GPS antenna
Robust Performance: ±1 dB accuracy, 0.11 dB resolution, strong EMI immunity
