PST2222 Distribution Lines Module



PST2222 Distribution Lines Module has 3 scaled down 3-phase Overhead Lines (OH) transmission lines (2 different) and one underground cable link with possibilities to change and combine impedance elements to constitute other OH High Voltages (HV) levels as well as cable models for distribution.

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.

With our Distribution 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.

Each model can either be studied as a six- or eight pole block or in itself component by component. 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.
