Omicron COMPANO 100 User Manual

2 Introduction
This application note describes the usage of COMPANO 100 together with CP
GB1 for measuring cable impedance and k-factors on short power cables (up
to 5 km) like used in urban and industrial environments.
Long cables and overhead lines can be not measured, as the COMPANO 100
test-set does not have sufficient output power for overhead lines.
WARNING
Death or severe injury caused by high voltage or current possible.
• Never connect COMPANO 100 directly to overhead lines or long power
cables. The open cable voltage on such systems is likely above the
maximum allowed level.
2.1 Safety Concept
The grounding box CP GB1 protects the user from unexpected events on the cable by being capable of
diverting high short-circuit currents. The insulation of the COMPANO 100 is designed to withstand far higher
voltages than the CP GB1’s surge arrestors do.
Always use measurement leads with a least 10 m / 30 ft length to connect COMPANO 100 to CP GB1, as
shown below. This limits the transients till the CP GB1 surge arrestors react.
Mark a danger zone around CB GB1. In open air systems, this must be at least 5 m / 15 ft distance from CB
GB1.
