7.3. Connection cable specifications
Connection cables from the MCTS rack to the
transducers are available in various cable lengths.
Special cable lengths can be manufactured
according demand. Be aware that the cable
resistance is part of the maximum measuring
resistance mentioned in the transducer data
sheets. The cables are available with two different
wire cross sections, 0.34 mm² and 0.75 mm².

7.3.2 Total Measuring Resistance at Full Scale
7.3.3. Maximum Burden Resistor depending on Transducer and Connection Cable
The remaining burden resistance can be calculated by subtraction of the connection cable loop resistance from the transducer total measuring
resistance.
Example IN 1000-S with 15 meters cable 0.34 mm² and 0.75 mm²:
IN 1000-
S total measuring resistance: 4 Ω at 1000 A
rms
MCTS/TPS/15 loop resi
stance: 3.14 Ω → Maximum burden resistor = 4 Ω - 3.14 Ω = 0.86 Ω
MCTS/TPS/15/0.75 loop resistance: 1.42 Ω → Maximum burden resistor = 4 Ω - 1.42 Ω = 2.58 Ω
