GD6000A Variable Frequency Dielectric Loss (Tan Delta) Tester

Overview: dielectric loss measurement is a basic insulation test that effectively detects overall moisture deterioration and local defects. The GD6000-A breaks through traditional bridge measurement, using frequency-conversion power technology, a single-chip microcomputer and modern electronics for automatic frequency conversion, A/D conversion and data computation.

Performance: the instrument provides strong anti-interference, fast testing, high accuracy, full automation and easy operation. It uses a high-power switch-mode supply outputting 45 Hz and 55 Hz pure sine waves with automatic voltage application up to 10 kV, and automatically filters out 50 Hz interference.

CVT capability: it supports CVT testing by the self-excitation method, with four protection limits (HV voltage/current, LV voltage/current), and can measure C1, C2 and the total capacitance and tan δ of CVT equipment. It also supports reverse-connection low-voltage shielding and non-disconnection 10kV reverse-connection tan δ measurement.

Safety: the instrument has grounding protection (no HV output if ungrounded or poorly grounded), over-current protection, and shock protection that immediately cuts off HV if the operator is shocked.
