The ST1000 is designed to measure the earth electrode resistance of Single Wire Earth Return Systems. It uses the SWER transformer (isolation or distribution) load currents to provide the measurement signals and accepts two CT inputs and one voltage input.
Testing can be carried out with the SWER in service and no disconnection of earth electrodes is required.
