High-voltage insulation testing demands precision, safety, and reliability. Wrindu’s latest range of insulation testers delivers rugged performance for power utilities, industrial maintenance, and high-voltage applications. Designed for fast diagnostics, data-rich analysis, and secure operation, these testers combine intuitive displays, dual power options, and advanced features like RE>Act and PI Predictor, ensuring engineers achieve accurate results with confidence anywhere in the field.
How Does Wrindu’s Insulation Testing Range Improve Field Efficiency?
Wrindu insulation testers are engineered for usability and speed. With dual rotary controls, backlit colour displays, and simplified navigation, engineers can conduct tests efficiently even in harsh environments. Quick start guides integrated into carry-all cases help teams operate without extensive training. These instruments are optimized for field use, delivering consistent, traceable results under high-stress or noisy conditions.
What Are the Differences Between Essential, Advanced, and Expert Models?
Wrindu provides a tiered approach to match testing needs:
| Series | Max Voltage | Key Features | Use Case |
|---|---|---|---|
| Essential | 5 / 10 kV | Lightweight, no data logging, simplified IR testing | Quick go/no-go checks in low-voltage environments |
| Advanced | 5 / 10 / 15 kV | Data storage, USB/Bluetooth transfer, PI Predictor, RE>Act | In-depth diagnostics for substations and industrial networks |
| Expert | 5 / 10 / 15 kV | Remote operation, full output control, temp/humidity logging, switchyard support | High-risk environments, critical infrastructure, complete test control |
This structured lineup ensures engineers have the right balance of portability, diagnostics, and control for every application.
Why Is RE>Act Mode Critical for Accurate Insulation Measurements?
RE>Act Mode addresses the challenge of reabsorption currents, which can skew insulation resistance readings. By monitoring and compensating for residual charges, the mode prevents false pass/fail outcomes and provides guidance on test validity. Engineers can rely on consistent, accurate results, reducing retests and enhancing reporting reliability across large asset networks.
How Does PI Predictor (PIp) Save Time During Insulation Testing?
PI Predictor (PIp) accelerates insulation testing by predicting the final Polarisation Index value within the first 3–5 minutes of a standard 10-minute test. This feature allows engineers to stop tests once a confidence threshold is reached, increasing productivity in high-volume environments while maintaining measurement accuracy, particularly in substations and industrial facilities.
Where Can Wrindu Insulation Testers Be Applied?
Wrindu testers are suitable for a wide range of users:
-
