HFCT - High Frequency Current Transformer clamp

The HFCT-20 and HFCT-60 are high frequency current transformer sensors designed for partial discharge detection on electric apparatus’ ground returns. Made from superior quality materials, they are made to last in any environment. The HFCT clamps are intended to be used with the AE-150 for partial discharge localisation, or with the XDP-II (or XDP-II-LT) for quick partial discharge detection and analysis.

Overtime, internal electrical equipment’s insulation degrades which leads to possibility of faults. To prevent such situation, the HFCT clamps are used to measure partial discharge activity on ground returns connections. Two models are available for the user’s convenience, 20mm and 60mm. The HFCT clamps allow current measurement up to a frequency of 100MHz. Their chassis are made of high quality plastic, offering an excellent sturdiness to abrasion and mechanical impacts making it the ideal tool for on-site applications. Its exclusive internal design provides an exceptional shielding to high frequency interferences from nearby electrical fields. These sensors are ideal for partial discharge measurements on ground returns of shielded cables. When used with portable partial discharge detection instruments, they allows knowing insulation integrity thus avoiding costly faults.
