This combination of ruggedness and portability means the Wrindu 60KV is not just a lab device—it’s a on-site testing workhorse that goes where your HV equipment is, delivering consistent performance no matter the environment.
Unmatched Precision: Industrial-Grade Accuracy for Early Defect Detection
The primary goal of HV insulation testing is to detect subtle insulation defects before they escalate into catastrophic equipment failures, which can cost industrial facilities thousands of dollars in downtime, repairs, and lost production. Generic VLF testers often compromise on accuracy, with ±5% or higher measurement error margins that miss these minor defects—putting industrial operations at risk.
The Wrindu 60KV is built for industrial-grade precision, with sensor technology and calibration that set it apart from all competitors:
- ±3% Voltage/Current Measurement Accuracy: Far superior to the ±5% accuracy of most generic VLF testers, this precision ensures that even small deviations in insulation performance are captured, allowing teams to address issues early and avoid unplanned downtime.
- 1×10⁻⁴ Tan Delta Accuracy: Tan delta testing is critical for measuring insulation loss in HV equipment, and the Wrindu 60KV’s ultra-precise tan delta detection identifies microscopic insulation degradation that lesser testers would overlook—extending the lifespan of your HV equipment.
- Unified High-Precision Sensors: Unlike traditional hipot testers that use separate sensors for each test type (leading to inconsistent data), the Wrindu 60KV uses a single set of calibrated, high-precision sensors for all integrated tests (AC/DC withstand voltage, tan delta, PD, DC leakage, capacitance). This ensures consistent, comparable data across all test types, making it easy to track insulation performance over time and identify trends.
- Calibration Stability: The Wrindu 60KV’s internal components are built for long-term calibration stability, meaning its accuracy remains consistent between annual calibrations—eliminating the need for frequent re-calibration and reducing downtime.
