PST2221 Transmission Lines Module



PST2221 Transmission Lines Module has 4 scaled down 3-phase OH transmission lines (3 different) with possibilities to change and combine impedance elements to constitute other Overhead Lines (OH) High Voltages (HV) levels.

All models have coils, capacitors and resistors designed to withstand overload and surges for dynamic as well as for static experiments.

All parameters of the transmission models can be changed easily by both internal and external combinations, together with the possibilities of arranging the models in series, parallel or in grid networks.

Each artificial line model consists of a three-phase pi-link and an earth link.

Technical Specifications

With our Transmission Line Modules, we have a unique combination of HV-lines, Medium-Voltage lines, OH-distribution Voltage lines and Distribution Voltage cables which will enable studies of the typical parameters and characteristics within the four main groups of AC-power transmission and corresponding need of compensation.

It is possible to isolate/separate the different R, L, and C characteristics of each line for individual analysis.

All line models have the same ratings in the model scale: 400 V, 2A.

All line models also have parallel four pole blocks to provide easy facilities of connection.
