Product Description

Heterodyne Dielectric Loss Tester

It breaks through the traditional bridge measurement method, adopts variable frequency power supply technology, and uses microcontrollers and modern electronic technology for automatic frequency conversion, A/D conversion, and data calculation, achieving strong anti-interference capability, fast test speed, high accuracy, full automation and digitization, and simple operation.

The power supply uses a high-power switching power supply, outputs 45Hz and 55Hz pure sine waves, automatically boosts voltage, and can provide up to 10kV voltage; it automatically filters out 50Hz interference, making it suitable for on-site testing in substations and other environments with strong electromagnetic interference.

Dielectric Loss Tester is widely used in the power industry for dielectric loss measurement of transformers, mutual inductors, bushings, capacitors, lightning arresters, and other equipment.

Product Features:

◆ It has multiple working modes: normal/reverse wiring, internal/external standard capacitor, internal/external high voltage, and an integrated structure. It can perform various conventional dielectric loss tests without any external auxiliary equipment.

◆ LCD display, menu operation, rich test data, automatically distinguishes capacitive, inductive, and resistive test objects, and comes with a built-in micro printer for printout.

◆ It has an external standard capacitor interface, can connect an external oil cup for precision insulating oil dielectric loss tests, can connect external solid material measuring electrodes for precision insulating material dielectric loss tests, and can also connect an external high-voltage standard capacitor for high-voltage dielectric loss tests.

◆ Automatically recognizes 50Hz / 60Hz system power supply, and supports generator power supply, so measurement can be performed normally even with large frequency fluctuations.

◆ Built-in series and parallel dielectric loss measurement models for easy instrument calibration.

◆ Can store 255 sets of measurement data.

◆ In CVT self-excitation method measurement, C1/C2 can be measured simultaneously with one connection, automatically compensating for the influence of busbar grounding and standard capacitor voltage division, without changing wires or connecting any external accessories.

◆ Chinese graphic menu, large-screen backlit LCD display for clearer viewing, real-time monitoring of current and voltage.

◆ Optimized circuit design makes the accuracy and stability of normal/reverse wiring consistent.

◆ Automatically recognizes external high-voltage test power supply frequency 40Hz～70Hz, supports power frequency power supply, variable frequency power supply, and series resonant power supply for large-capacity high-voltage dielectric loss tests.
