Name: SY8330E Three Phase Energy Meter Test Bench
Brand: SONGYANG

Overview

The SONGYANG SY8330E is a fully automatic three-phase energy meter close-link test bench for utilities, meter manufacturers and calibration laboratories. It supports common single-phase and three-phase wiring systems and uses an insulation current transformer (ICT) for close-link meter testing.

The manufacturer brochure lists compliance with IEC 62057 Part 1, IEC 62052 and IEC 62053. Select the final configuration according to the meter type, number of positions, current range, reference meter and local mains supply.

Supported Meters and Tests

The bench supports 1P2W, 1P3W, 2P3W, 3P3W and 3P4W meters, including active and reactive energy meters, electronic meters, multifunction meters and four-quadrant power meters.

Supported procedures include warm-up, basic error, standard deviation, repeatability, no-load, starting, phase rotation, voltage and current unbalance, voltage and frequency influence, 24-hour deviation, harmonic influence and neutral-current function tests.
