LQSS-29 Dielectric Loss Calibrator | 29-Step HV Bridge Validator

Engineered for ultra-precise high-voltage measurements, the LQSS-29 Standard Dielectric Loss Calibrating Device features an industry-leading 29-point calibration range and integrated 50kV/100pF SF6 reference capacitor (1×10⁻⁵ tan δ). The ultimate solution for power utilities and HV labs.

Key Innovations

• 29 Calibration Grades: 1×10⁻⁴ to 1×10⁻⁵ with 0.1×10⁻⁴ increments

• High-Voltage Reference: 50kV SF6 capacitor (3× industry standard voltage)

• Diagnostic Precision: Isolate measurement errors to ±0.5%

• Field-Ready: MIL-STD-810G rated for harsh environments

4-Step Calibration Process

1. Connect: HV leads to bridge (Doble/OMICRON compatible)

2. Select: Target grade matching test voltage

3. Measure: Compare against reference values

4. Adjust: Bridge calibration if >±1% deviation

Compliance & Standards

• IEC 61869-11 Class A (Measurement)

• IEEE 4-2021 (HV Testing)

• ANSI/NETA ATS-2023 (Field Acceptance)

Why LQSS-29 Stands Out

• Unmatched Resolution: 29 steps vs. competitors' 5-11

• Higher Voltage: 50kV reference (vs. typical 10kV)

• Military Durability: Vibration/shock resistant
