The dielectric loss (dissipation factor) measurement device Tangens-3M-3 is designed to measure the dielectric loss tangent (tan delta) of transformer oil and other liquid dielectrics.
Under the normal conditions, the device Tangens-3M-3 provides the measurement of the dielectric loss tangent (tan delta dissipation factor) (tgδ) and the capacity of liquid dielectric samples (Сх) in the ranges with basic measurement error given below:
·measurement range of dielectric loss tangent – from 1·10-4 to 0.99;
·limit of permissible absolute basic error when measuring the dielectric loss tangent1) – +(2·10-4 + 0.05 tgδ)%;
·range of capacity measurement at a test voltage – from 1.5 to 2 kV from 5 pF to 100 pF;
·limit of permissible basic error when measuring the capacity at a frequency of 50 Hz – 1 pF+0.01 Сх;
·limit of permissible basic error when measuring the capacity at a frequency of 54 Hz – 1 pF+0.03 Сх;
·limit of measured liquid temperature deviation from the preset temperature, °С, – +1;
·limit of permissible absolute basic error when measuring the dielectric loss tangent2) – +(2.5·10-4 + 0.07 tgδ);
·limit of permissible relative error when measuring the RMS voltage value at a frequency of 50 Hz in the voltage measurement range – from 1 to 2 kV +3%;
·limit of permissible relative error when measuring the RMS voltage value at a frequency of 54 Hz in the voltage measurement range – from 1 to 2 kV +3%;
·limit of permissible absolute measurement error of the measured liquid dielectric temperature – +1 °С;
·heat time up to 90°C, min, – 80±20;
·cell volume, cm3, – 60±2;
·single-phase AC supply voltage, V, – 220±22;
·power consumption, W, max, – 0.6.
1 – for the full range of capacity measurement at a test voltage frequency of 50 Hz;2 – for the full range of capacity measurement at a test voltage frequency of 54 Hz.
