STS 5000 Multifunction substation test set

STS 5000 is a multifunction substation maintenance & commissioning test system for current, voltage and power transformers designed to perform primary tests requested in substations commissioning. It allows to perform accurate tests on CTs, VTs, PTs and ground grid. Main features Fully automatic Primary injection testing capabilities: up to 800 A or up to 5000 A / 7000 A, with the optional module BUX 5000 Variable output frequency: 15 – 500 Hz Power dissipation factor test with the optional module TD 5000 ( voltage up to 12 kV) 2000 v AC high-pot test Local control by large color display PADS – Power Apparatus Diagnostic Software for automatic testing, assessment and report IEC 61850-9-2 communication protocol Patented technology for Capacitance and Tan Delta measurement USB interface and Ethernet interface for PC connection.
