TANDO 700
Precision tan delta and capacitance measurement system for assessing insulation condition of bushings, transformers, and HV equipment.
TANDO 700 is a highly accurate test system for measuring capacitance and dissipation factor (tan delta) in high-voltage insulation systems. It is commonly used on transformers, bushings, instrument transformers, and cable terminations to assess insulation aging and moisture content. With superior accuracy and long-term stability, TANDO 700 ensures reliable measurements that comply with IEC and IEEE standards. Its robust filtering technology provides stable results even in electrically noisy environments such as substations. The intuitive test software offers guided workflows, automated calculations, and report generation for efficient field operations. TANDO 700 integrates seamlessly with OMICRON’s primary testing ecosystem, making it a trusted tool for commissioning and advanced diagnostics.
