Applications in Power Grid iTest S860 Acoust ic Camera • 128 MEMS microphones • Locating defects (electrical, vibration, leakage) • One-handed operation for flexibility • 8 megapixel HD camera clearly shows defects •Real-time display of the discharge level on screen •Automatic determination of the type and severity of PD according to tested equipment •Testing frequencies from 2kHz-65kHz •Testing range from 0.3 m-100 m •Photos and videos for recording abnormal spots Why is acoustic imaging testing necessary? The grid system has many devices and a complex structure. With the growth of equipment operation time, equipment gradually aging. It is easy to cause faults in equipment, resulting in large area blackouts, reducing the reliability of the entire grid and causing inconvenience to society. How acoustic cameras detect power equipment? Based on the anomalies localized on screen of the acoustic camera, which become more visible as the electrical equipment deteriorates. It also has a multipoint detection mode, which effectively covers every hidden area and improves detection efficiency. How to determine defects? If there are obvious acoustic signal on the equipment, this indicates an anomaly. The abnormal electrical equipment should be repaired or replaced according to the outage plan. If there are multiple anomalies , the defect is serious and needs to be repaired or replaced as soon as possible. Can I see multiple anomalies on the screen? Multiple partial discharge, abnormal vibration, or leakage can be displayed simultaneously Methods for detecting live equipments UV Camera, IR Camera, All-in-one PD detector Tel: + 86-21-6590 2995 E-mail: info@infratest.com.cn Website: en.soundw.com.cn Address: A13, South Area, Building 8, No. 619 Longchang Road, Yangpu District, Shanghai, China 200082
