2 "Goliath" can be used in various applications where low cost, reliability and small dimensions are needed (for example, in power distribution networks for single-phase ground fault detection, as a component of a portable laboratory for carrying out field testing of HV power networks and other HV installations). A 100 kV "Goliath" test specimen has been manufactured. The specimen has successfully passed testing as a component of a traveling HV laboratory (in a motor car) and also can be used in powerful radio transmitters, electro-physical units, in test beds and HV technological applications.

As core 10 leaves upper winding 14, its inductive reactance is considerably reduced, and the current is increased, illuminating light diode 25, which induces the device activation. The device is switched off by pressing and releasing "STOP" button 23. 2). 4 Circuit diagram of single "Goliath" control unit when three-channel (A, B, C) switch-gear is assembled from separate "Golialh" units. Kl - control relay for inside command "OFF"; K2 - control relay for inside command "ON"; RS-1 (blocking) and RS-2 (indication) - inside reed switch contacts sensitive to "Goliath" ferromagnetic core position.
