Abstract:
In the field of high voltage direct current power transmission and distribution there is provided a converter which includes first and second DC terminals for connection to a DC electrical network and between which extends converter limbs. Each converter limb includes first and second limb portions that are separated by an AC terminal for connection to a respective phase of a multi-phase AC electrical network. Each limb portion includes a current sensor to measure current flowing in the corresponding limb portion. The converter also includes further current sensors, located elsewhere in the converter, and a current sensor management unit. The current sensor management unit is programmed to: receive a measured current value from each current sensor; identify at least one faulty current sensor from the received measured current values; and replace the measured current value of the or each identified faulty current sensor with a calculated current value.

Claim (Index 7):
The converter according to  claim 1 , wherein the current sensor management unit is programmed to uniquely identify all possible pairs of faulty current sensors from the received measured current values by:\n establishing a respective sum of measured current values at each of an extended number of junction locations within the converter, the extended number of junctions being larger than the initial number of junctions; detecting an error in a respective sum of measured current values when the sum differs from a corresponding threshold current value; establishing an error pattern representing the or each erroneous sum detected; comparing the error pattern with a predetermined extended error reference defining all possible error patterns corresponding to faulty pairs of current sensors; and identifying a given pair of faulty current sensors by matching the established error pattern with an identical corresponding possible error pattern in the extended error reference.
