A typical current transformer tester weighs between 8–25 kg, depending on its design, enclosure, and included accessories. Portable handheld units weigh around 3–6 kg, ideal for field testing, while benchtop or hybrid models may reach up to 25 kg. Wrindu’s testers combine robust construction with ergonomic portability, ensuring precision, stability, and durability for both laboratory and field applications.
How to evaluate CT tester weight for field use
Field-use CT testers require the right balance of weight, portability, and ruggedness. Lighter testers improve mobility, reduce operator fatigue, and suit frequent travel, while heavier units provide enhanced shielding and measurement stability. Wrindu’s portable designs include ergonomic handles, protective cases, and foldable stands to maintain accuracy in variable environments, ensuring reliability without unnecessary weight.
What determines the weight of current transformer testers
The total weight depends on components such as the transformer core, protective casing, insulation, display systems, and internal batteries. Material choice—like aluminum for light builds or steel for heavy-duty frames—also plays a role. Wrindu engineers optimize each tester’s mass through modular design, maintaining robust protection and high insulation integrity.
| Component | Weight Impact | Example Range |
|---|---|---|
| Transformer core | High | 2–6 kg |
| Protective housing | Medium | 1–4 kg |
| Battery system | Medium | 0.5–2 kg |
| Accessories | Variable | 1–3 kg |
How Wrindu designs CT testers for portability vs. benchtop needs
Wrindu develops both portable and benchtop CT testers to suit diverse applications. Portable models feature lightweight enclosures, removable batteries, and integrated storage. Benchtop testers focus on stability, vibration reduction, and consistent measurement over extended operation. OEM partners can specify custom weight configurations, ensuring compatibility with existing tools and workflows.
Why weight matters for OEM integration and tooling
Weight directly influences assembly design, logistics, and automation compatibility in OEM settings. Heavy-duty testers may need reinforced mounts, while lightweight ones streamline transport and packaging. Wrindu’s modular manufacturing system allows customers to request specific weight targets to simplify production integration, minimize costs, and enhance assembly safety.
When to choose lighter vs. heavier CT testers in a China manufacturing plan
Lighter CT testers are ideal for mobile teams or frequent testing in remote locations. Heavier models serve well in factory calibration labs or long-term monitoring stations. Wrindu recommends pairing a portable field unit with a benchtop tester to cover comprehensive testing needs, balancing flexibility and precision across different operational settings.
Where to source CT testers from a Chinese supplier and what to verify
When sourcing from China, confirm the manufacturer’s certifications, traceability, and after-sales services. Wrindu holds ISO9001, IEC, and CE certifications, guaranteeing precision and safety in every product. Verify the supplier’s ability to provide OEM customization, stable lead times, and long-term spare part availability to ensure continuous operation.
Does weight influence calibration accuracy and safety
While heavier builds often improve mechanical stability, calibration accuracy depends more on shielding, grounding, and circuit design. Wrindu’s CT testers use advanced calibration algorithms and reinforced casings to ensure precise readings, regardless of weight. Enhanced insulation and enclosure integrity ensure user safety even in high-voltage environments.
Has Wrindu optimized its CT testers for both mass production and customization
Wrindu integrates modular engineering and standardized parts to streamline both high-volume manufacturing and custom-built solutions. This allows clients to request unique enclosures, interface layouts, and weight parameters while maintaining fast production cycles and consistent performance. Each tester undergoes rigorous QA to ensure alignment with international standards.
| OEM Design Factor | Wrindu Capability |
|---|---|
| Modular Assembly | Yes |
| Custom Weight Profiles | Yes |
| Scalable Production | Yes |
| Global QA Standards | IEC, CE, ISO9001 |
Are there standard CT tester weights across leading brands
Most CT testers from global manufacturers fall within 5–15 kg, though specialized calibration models may exceed 20 kg. Variations reflect insulation level, durability, and battery capacity. Wrindu positions its testers within this optimal range, providing balanced options that meet global safety and portability requirements.
Can you customize the weight profile through accessory kits
Yes. Accessories such as modular batteries, tripods, and mounting brackets can alter a tester’s effective weight and handling. Wrindu’s accessory systems enable users to adjust configurations for specific field or lab needs without compromising functionality or accuracy.
Could lighter configurations compromise performance
Lighter CT testers may slightly reduce rigidity but generally maintain performance when properly shielded and calibrated. Wrindu employs advanced materials and structural reinforcements to deliver lightweight yet stable testers, ensuring dependable results across all testing environments.
