Abstract
A device including a diversion circuit and a harvesting circuit, wherein the diversion circuit includes at least two parallel connected protection branches between a surge arrester and ground. The at least two protection branches include at least one TVS device and at least one impedance connected in series with the at least one TVS device. The diversion circuit is configured to divert leakage current through the harvesting circuit and bypass the harvesting circuit and lead surge current via the at least one parallel connected protection branch to ground, during a surge event, to protect the measurement circuit.
