Dielectric loss measurement unit

without Tangent-2000

The IDP block 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:

• Preparation for insulation parameter meter Tangent-2000;
• High-voltage switch “DIRECT-INVERSION”.

A special feature of the Tangent-2000 meter is the absence of galvanic connection between the high-potential measuring and low-potential indicator circuits, which ensures complete operational safety. Data from the measuring unit to the display module is transmitted via a radio channel. The meter also has high noise immunity.

The IDP block makes it possible to carry out measurements using “direct” and “inverse” (“inverted”) measurement schemes, which ensures the measurement of insulation parameters of objects with both isolated and grounded terminals.

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 2 sections (“External equipment connection panel”, “Low-voltage measurement panel”) and performs the following functions:

1. Connection of external equipment up to 2.5 kV to the test object (L1, N);
2. Connecting measuring instruments to the test object 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.
