EPJS-6000 is a new generation, fully automatic on-site measure dielectric loss(tgδ)and the capacitance (Cx) of electric equipment. It's suitable for testing on transformer, insulating bush, capacitor, CT/PT, MOA etc.
Features:
- Build-in dielectric loss bridge, frequency conversion power supply, testing transformer, SF6 high stability standard capacitor.
- The test high-voltage source is generated by the inverter inside the instrument and is used for the test object after boosting the voltage from the transformer.
- Frequency can be changed into 50Hz, 47.5Hz/52.5Hz, 45Hz/55Hz, 60Hz, 57.5Hz/62.5Hz, 55Hz/65Hz. Digital notch technology is adopted to avoid the interference of power frequency electric field to the test.
- Multiple protection of input voltage fluctuation, output short circuit, over-voltage, over-current, temperature, secure and reliable. Meanwhile, it has the function of grounding testing, that voltage boost is not permitted for non-grounding equipment.
- LCD touch screen display. English menu easy to operate.
- 200 groups' data storage. Save testing result according to time order, check history record and print the result.
- Multiple testing mode, with modes of inside high voltage, outside high voltage, inner standard, external standard, GST/UST, self-excitation. High voltage (more than 12kV) dielectric loss test can be made in the situation of external standard outside high voltage.
- Test full sealed CVT (Capacitive Voltage Transformer) C1 and C2 dielectric loss and capacitance at the same time. Also test CVT transformation ratio and voltage angle difference.
- The instrument can accurately measure the CVT dielectric loss value and capacitance value without removing the CVT high voltage lead.
- The dielectric loss and capacitance value of C0 in the upper end of CVT can be measured by using the reverse shielding method.
- High speed sampling signal. Inverter and sampling circuit inside are digitized controlled. Output voltage is adjusted continuously.
