LQSS-8 Dielectric Loss Calibrator | Tan Delta Bridge Validation Device

Engineered for precision verification of high-voltage tan delta bridges, the LQSS-8 Standard Dielectric Loss Calibrator provides 8 accuracy grades (from 1×10⁻⁴ to 1×10⁻⁵) with an integrated 10kV/50pF SF6 reference capacitor. Eliminates the need for external calibration services.

Key Features

• 8-Point Calibration: Validates tan δ bridges across full measurement range

• Integrated SF6 Standard: 10kV gas-insulated capacitor (1×10⁻⁵ reference)

• Field-Ready Design: Portable for lab and onsite transformer/cable testing

• Diagnostic Mode: Identifies measurement deviations in HV test sets

How It Works

The LQSS-8 serves as a known reference for dielectric loss measurements:

1. Connect to tan delta bridge (HCL 2876, etc.)

2. Select calibration grade (1-8)

3. Compare readings against reference values

4. Identify measurement deviations >±1%

Why Choose This Calibrator?

• Cost Savings: Avoids $3k+/year in third-party calibrations

• Time Efficiency: On-demand verification in 15 minutes

• Traceability: SF6 capacitor meets IEC 61869-11 standards
