Datasheet for Multifunction substation test set STS 5000
The ISA STS 5000 Multifunction Substation Test Set combines several electrical test functions in one system. It includes high AC current, low AC current, high DC current, low DC current, high AC voltage and low AC voltage outputs.
For example, users can test current transformers for ratio, polarity, excitation curve, knee-point voltage, winding resistance and secondary burden. Similarly, the system supports voltage transformer and potential transformer tests.
For power transformers, it measures winding resistance, short-circuit impedance, leakage reactance and no-load current. In addition, it supports on-load tap changer (OLTC) dynamic resistance tests.
The system also offers micro-ohmmeter functions. Moreover, it can measure circuit breaker operation time. Furthermore, it supports IEC 61850-9-2 communication for compatible test setups.
Its graphic display helps users control tests and view results. In addition, USB and Ethernet ports allow data transfer and PC connection. Thus, the STS 5000 supports several substation test tasks.
The STS 5000 uses built-in electrical output and measurement systems to perform different substation tests. Moreover, its variable frequency output ranges from 15 Hz to 500 Hz. Therefore, engineers can select the right test frequency for their needs.
The system provides primary current injection up to 800 A. In addition, users can connect optional BUX current boosters to increase the current output. As a result, the system can support different current injection needs.
Furthermore, the optional TD 5000 module adds capacitance and Tan Delta tests. It supports test voltages up to 12 kV. Therefore, engineers can check the insulation of electrical equipment.
The system also works with PADS software. This software supports automatic tests and report creation. Moreover, it helps users save and review test results. USB and Ethernet ports also support data transfer.
In addition, automatic test functions help reduce manual work. Consequently, engineers can carry out tests in a more organised way. Thus, the STS 5000 supports substation testing, commissioning and maintenance.
