These impulses travel along the equipment earth to the substation earth.
Using a high frequency current transformer they can be detected as they pass through the CT.
The HFCT100/50 has a split core ferrite to allow retrospective fitting to earth straps without the need for disconnection.
The durable body has a hinge and a quick release latch making use quick and easy.
The CT is constructed with an aluminium body to provide RF shielding and improved performance in noisy environments.
This transducer is ideal for all earth and neutral PD monitoring applications.
