Advanced Vector Testing with SMG8000 Six-Channel DifferentialProtection Analyzer

In the field of electrical power system testing and maintenance, accurate measurement and analysis of current and voltage vectors are essential, especially for differential protection systems. Traditional methods often require multiple instruments and tedious manual calculations to assess parameters such as phase angles, power values, and unbalance conditions. The SMG8000 Six-Channel Differential Protection Vector Tester introduces a significant advancement by integrating multi-channel measurement and automated analysis in a single portable device.

Unlike conventional test sets that sample voltages and currents separately or lack simultaneous high-side and low-side measurement capability, the SMG8000 can measure up to three AC voltages (secondary), three AC currents (secondary), and three AC currents (primary) all at the same time. This allows engineers to directly obtain key parameters including phase shifts between primary and secondary currents—a critical requirement in differential protection testing.

Key features include:

• Measurement of frequency, active power, reactive power, apparent power, and power factor.

• Unbalance analysis for three-phase voltage and current systems.

• Built-in vector diagram display (hexagonal graph) with mixed primary and secondary quantities.

• High accuracy with 24-bit ADC, DSP processing, and touchscreen interface.

• Data export via USB in Word and Excel formats without requiring PC software.

• Support for an external micro-printer for instant report generation.

Technical specifications further highlight its capability:

• Voltage: 1–500 V, ±0.5% FS, 0.01 V resolution

• Primary Current: 0.1–5 A, ±0.5% FS, 0.0001 A resolution

• Secondary Current: 0.001–10 A, ±0.5% FS, 0.0001 A resolution

• Power Measurements: 0.001–5 kW/kVAR/kVA, ±0.5% FS

• Frequency: 45–65 Hz, ±0.1% FS

• Phase Angle: 0–360°, ±1° accuracy

Compared to older test systems, the SMG8000 offers integrated functionality, better accuracy, and user-friendly automation—making it an ideal tool for protection engineers and technicians involved in commissioning and maintaining differential protection systems.
