Product Description

1. Introduction

SY8330 Series Three Phase Energy Auto-calibration System is a new generation, high precision, multifunctional energy meter calibration equipment. It uses the international’s most advanced technology and components available in 90 decade. It can be widely used to calibrate different kind of single phase energy meter both channel & three phase energy meter or multifunction power meter.

2. Function

  • Warm up
  • Basic error test
  • Standard deviation (S) in error test
  • Repeatable error test
  • Latent test (no load test)/automatic/manual
  • Initial test (starting test)/automatic/manual
  • Voltage influence testing
  • Voltage unbalance testing
  • Individual current reversal testing
  • Phase rotation testing
  • Frequency influence testing
  • Deviation test for 24 hours
  • Harmonic testing
  • Phase circuit testing with close link (channel of single phase meter)
  • Neutral circuit testing with close link (channel of single phase meter)
  • Neutral missing testing (channel of single phase meter)
  • Current by pass testing option for three phase meter
  • Neutral current testing option for three phase meter
  • Single phase meter balance condition testing with closed link
