Introduction to Parameters of BQS-37a Power Frequency Dielectric Constant Dielectric Loss Bridge

BQS-37aThe Type High Voltage Bridge is a new generation high-voltage bridge launched by our company, mainly used to measure the dielectric loss (tg δ) and dielectric constant (ε) of industrial insulation materials. The test method for AC loss characteristics and dielectric constant of solid electrical insulation materials in accordance with GB1409, GB5654 and GB/T1693, ASTM D150-1998 (2004) adopts the classic circuit of the Xilin bridge, which is equipped with a 0-5000 digital high voltage power supply and a 100PF standard capacitor, and can be expanded with an external standard capacitor circuit according to user requirements.

Characteristics of 1-2 bridge;

The bridge body is equipped with a potential tracker and a zero point indicator, with minimal peripheral wiring.

The bridge adopts a ten pin switch with low contact resistance and long mechanical life to ensure measurement stability

The instrument has dual shielding, which can effectively prevent interference from external electromagnetic fields.

The internal resistance and capacitance components of the instrument have undergone special aging treatment to ensure stable and reliable technical performance.
