Product Description
GF106 Transformer Test Equipment Application To protect class or measuring kind of transformer characteristics (CT and PT) for automatic test, suitable for the laboratory also applies to the field detection. GF106: test CT and PT GF106A: test CT GF106B: test PT Reference Standard GB 1207-2006, GB 1208-2006 (IEC 60044-1), GB16847-1997 (IEC 60044-6) Main features • Support to detect CT (protection type, measuring kind, TP class) steady state and transient parameters; • To use advanced frequency conversion power technology, (current-voltage characters) excitation inflection point voltage up to 30 KV; • No external other auxiliary equipment, single machine can complete all testing project; • Using intelligent controller, simple operation; • LCD, graphical display interface; • According to the regulations, automatically give (excitation) inflection point value; • Automatically give 5% and 10% error curve; • saving 3000 test data, not lost after power off; • Support U plate archived data, using a standard PC to read data,and produce WORD report; • small light ≤10 Kg, it is very easy to the field test; • Support to detect the error of PT at the same time. Main functions CT (PT) (protection type, measuring kind, TP class) • current-voltage characters curve (excitation characteristic) • automatically give inflection point value • automatically give 5% and 10% of the error curve • variable ratio measurement • Ratio error measurement • phase angle measurements (angular) • polar judgment • the secondary winding resistance measurements • two times the actual load measurement •Core demagnetization, • accurate limit coefficient (ALF) • instrument security coefficient (FS) • second time constant (Ts) • residual magnetism coefficient (Kr) • saturated and unsaturated inductance Technical Data Project Parameter Power supply AC220V±10% 、50Hz Equipment output 0～150Vrms， 5Arms（15Apeak ） Voltage measurement accuracy ±0.1% The secondary winding Resistance measurements range 0～50Ω accuracy 1%±1mΩ Two times the actual Load measurement range 0～300VA accuracy 1%±0.1VA Phase measurement (angular) accuracy ±3min resolution 0.3min CT Variable ratio measurement range 1-10000 accuracy ±0.05% PT Variable ratio measurement range 1-10000 accuracy ±0.05% Work environment Temperature:-10 ℃ ~ 40 ℃, humidity:≤ 90% or altitude ≤1000 m Size, weight Size: 380 mm x 240 mm x 180 mm, weight: ≤10 kg
