Product description

Product Overview
Transformer live testing is an important electrical diagnostic method, crucial for assessing the insulation condition and reliability of transformers. It can reveal potential insulation defects or damage inside the transformer. By analyzing the characteristics of partial discharge, this method helps identify internal issues such as air bubbles, impurities, or burrs on metal components within solid insulation—common culprits behind partial discharge events.

Ultrasonic Testing

Ultrasound testing captures and analyzes ultrasonic signals generated by partial discharges, allowing for unrestricted measurement points and simple localization. It can detect defects such as free particles, burrs, and poor contact.

Ultra-High-Frequency Detection

The ultra-high-frequency detection method uses antenna sensors to receive UHF electromagnetic waves emitted during partial discharge, offering high sensitivity and enabling precise localization of the discharge source.

High-Frequency Current Detection

The high-frequency current detection method uses a high-frequency current sensor to detect high-frequency pulse signals flowing through grounding down conductors or other ground potential connection lines, enabling live detection of partial discharges in power equipment.

Infrared Detection

Infrared thermography can measure the temperature distribution across surfaces, particularly in areas such as windings, terminal blocks, and cooling systems. By comparing and analyzing the temperature data, it becomes possible to identify issues like overheating and poor heat dissipation caused by material aging in equipment.

Ground Current Detection

The core and clamp grounding current test can accurately determine whether the core or clamps have multi-point grounding faults.
