SOUKOU TA-1020 tan δ Tester (Dielectric Loss of HV Equipment) | AC 0–10 kV, 150 mA, 1.5 kVA, tan δ 0.1–19.9%

SOUKOU TA-1020 tan δ Tester: Insulation Diagnosis of High-Voltage Equipment

Overview

The TA-1020 is a tan δ tester developed by Soukou Electric (SOUKOU) for diagnosing high-voltage equipment (PTs, CTs, transformers, etc.). It assesses insulation deterioration from tan δ (dielectric loss tangent) and leakage current. The manufacturer states that it cannot be used for CV cable diagnosis. The manufacturer's page also provides assessment guidance: deterioration is evaluated from changes in tan δ and charging current with temperature, with voltage (stepping up and down over 1000–4000 V) and over year-to-year measurements.
