Dielectric loss measurement unit

(without bridge)

The IDP unit provides measurement of the capacitance and dielectric loss tangent of test objects at an alternating current voltage with a frequency of 50 Hz up to 10 kV within the limits provided by the Tangent-2000 meter.

The IDP block includes:

• Place for AC bridge type Tangent2000;
• High-voltage switch “DIRECT-INVERSION”.

Switching occurs in a high-voltage switch “DIRECT-INVERT”. The switch allows, after starting the test in the IDP mode, to switch the measurement circuit without re-switching the high-voltage conductors.

Low voltage connection block

The low-voltage connection block is divided into 4 sections (“GZCH control panel”, “Reflectometer connection panel”, “External equipment connection panel”, “Low-voltage measurement panel”) and performs the following functions:

1. Audio frequency generator control;
2. Connecting external equipment up to 2.5 kV to the test object;
3. Connecting the reflectometer to the test object;
4. Connecting measuring instruments to the test object (power transformer) in three-phase mode (400V/10A).

Rack for connections to BNI

The laboratory is equipped with a free-standing rack for connecting cables to the BNI unit in the high-voltage compartment.

The rack contains connectors for connecting low-voltage test cables and external power supply to a three-phase autotransformer. All low-voltage test cables are protected by 10A fuse links against exceeding the maximum current and voltage of 400V. Fuse links are grouped near the corresponding connectors.
