STS 5000/STS 4000 & STSG – STLG -MULTIFUNCTION SUBSTATION MAINTENANCE & COMMISSIONING TEST SYSTEMS FOR CURRENT, VOLTAGE AND POWER TRANSFORMERS
This primary current injection testing system is designed to perform primary tests requested in substations commissioning. It allows to perform accurate tests on CTs, VTs, PTs and ground grid.
- Fully automatic
- Primary injection testing capabilities: up to 800 A or up to 3000 A, with the optional module BUX 3000
- Variable output frequency: 15 - 500 Hz
- Local control by large color display
- PADS - Power Apparatus Diagnostic Software for automatic testing, assessment and report
- IEC 61850-9-2 communication protocol
- Optional line impedance test kit, made of:
- STLG - line and grid module;
- STSG - safety grounding module
- The option allows performing the measurement of:
- soil resistivity
- ground grid resistance
- step and touch tests
- STSG protects the operator against possible high voltage spikes.
- USB interface and Ethernet interface for PC connection.
- Compact and lightweight.
