UHV-342 Transformer capacitance & tan delta tester is mainly used for measure the transformer’s capacitance and tan delta value, it has the feature:
1 With forward/reverse connection, internal/external standard capacitor, internal/external high voltage, multiple working modes and integrated structure, it can do all kinds of conventional dielectric loss test and insulation resistance measurement without any external auxiliary equipment.
2 It has external standard capacitor interface, which can automatically track the frequency of external test power supply from 40Hz to 70Hz, supports power frequency power supply and series resonant power supply to conduct large-capacity and high-voltage dielectric loss test.
3 It has the function of reminding the circuit of bad contact discharge, so as to determine whether the connection is reliable or not.
4 With CVT self-excitation measurement function, C1/C2 can be measured at the same time by wiring, and automatically compensate for the influence of bus grounding and voltage division of standard capacitor. There is no need to change the wire and connect any accessories externally, and the high-voltage connection line can drag the ground.
5 With the function of CVT variable ratio, CVT variable ratio, polarity and phase error can be measured.(optional)
6 It has anti-wiring low-voltage shielding function. Under the condition of 220kVCVT bus grounding, 10kV anti-wiring dielectric loss measurement can be carried out on C11 without disconnecting the wires, and the main and subordinate capacitors can be measured at the same time with one connection.
7 English text and text menu, large-screen backlight LCD display.
8 Equipped with thermal printer, the printing data is clear, fast and noiseless.
9 With calendar clock, can store 100 sets of measurement data.
10 With computer interface. Through this interface, measurement, data processing and report output can be achieved, and internal measurement software can be upgraded. A computer can control 32 instruments, which can be integrated into the comprehensive high-voltage test vehicle.
11 With the function of four-channel forward connection, the transformer bushing can measure three bushing of A/B/C at one time, saving time and effort (function optional)
