Wood heating system and method

A method for obtaining an electro-thermal model of a wood length comprising:

• connecting a first electrode assembly to one end of the wood length and connecting a second electrode assembly to the other end of the wood length, at least one of the first and second electrode assemblies comprising a plurality of electrode segments;
• and
• energizing the plurality of electrode segments of each electrode assembly to determine current and/or voltage distributions from an electrical sensor in the plurality of electrode segments to obtain an electro-thermal model of the wood length.

An apparatus for treating a wood length comprising:

• a controller configured to energize a first and a second electrode assembly, at least one of the first and second electrode assemblies comprising a plurality of electrode segments, connectable to a first and a second end of the wood length;
• a measurement system comprising electrical sensors associated with each of the plurality of electrode segments, the measurement system configured to determine current and/or voltage distributions across the first and/or second end of the wood length;
• a treatment system configured to treat the wood length to the target temperature.
