Applications and Importance in Bangladesh
There are several things to consider when performing insulation testing in Bangladesh’s electrical and industrial infrastructure:
- Humidity and Environmental Challenges: Rain, dust and humidity are high in many parts of Bangladesh — insulated parts degrade quickly. Therefore, insulation resistance needs to be tested regularly.
- Various types of installations: Solar power parks, telecommunication towers, industrial machinery, building switchgear rooms — checking insulation resistance everywhere increases safety.
- Maintenance and safety audits: Not only new installations, but also regular maintenance and safety audits require insulation testers.
- More difficult tasks: Insulation testing can be difficult in old cables, contaminated soil, long installation lines, etc. — here a high range tester is important.
As discussed above, the Kyoritsu3125B is a suitable instrument for these needs: because it comes with high voltage testing support, powerful resistance measurement and filtering and safety features. It can be considered a kind of “reliable solution” in Bangladeshi commercial/industrial settings.
Where to use the Kyoritsu3125B?
- New installation testing: To ensure insulation resistance in large electrical installations such as substation transformer rooms, cable trunking lines.
- In maintenance operations: To check whether the insulation resistance has become low over time.
- Safety audit and compliance checking: To record the insulation resistance according to international or national safety standards.
- Special size in high voltage series: Because it supports voltage range of 5kV or more — convenient for testing large components or line cables.
- Insulation health checking of other equipment: Such as motor windings, generator stators, cable sheaths and insulated sub-systems.

Why is this comparison important?
This comparison table helps you make a decision by looking at all the brands together: model-specific voltage range, resistance capacity, features, and functionality to help you choose the most suitable instrument for your project. For example: If your job involves insulation testing large lines where voltages of 5kV or more are required — then consider the Kyoritsu3125B or Megger’s high voltage models. If it’s general maintenance or small systems — then a lower voltage range model may be sufficient.
Why is the Kyoritsu3125B a good choice?
- High voltage test range: 250V to 5000V, This is suitable for large installations.
- Strong insulation resistance range: up to GΩ bracket, This range is needed when the insulation is in very good condition, but the residual resistance is very high.
- User-friendly design and field-useable features: Large display, backlight, filter function, live voltage warning, which works well in the harsh environment of Bangladesh.
- Brand reliability and support: It is easy to get service and manufacturer support for instruments from brands like Kyoritsu.
- Suitable for scheduled maintenance and inspection activities: If you regularly perform insulation tests, want to keep a record of measurements, reduce the risk of errors, then this instrument is very useful.
What are the important things t
o keep in mind?
- Voltage range: How much voltage is required for your work — if it is only 1000 volts, then you may not need a full 5000 volt unit.
- Resistance measurement range: In the case of old or well-insulated parts, the resistance is much higher — GΩ or TΩ level readings may be required.
- Service and manufacturer support: Make sure that the instrument has after-sales service and calibration facilities.
- Accessories and Casing: It is better to have good quality casing, leads, probes in field installations.
- Environmental suitability: When working in high humidity, dust or open installations, the unit is at risk of rust or breakdown — good build quality reduces that risk.
- Ease of operation and reading: Large display, backlight, clear leads and reading features make work faster.
Bangladeshi reality and application examples
Solar power installation: Solar farms and rooftop solar systems are growing rapidly in rural and urban areas of Bangladesh. Insulation testing is very important here because solar panels, inverters and grounding structures are at risk due to the environment. Units like the Kyoritsu3125B are becoming ideal for insulation health checks, including lightning resistance.
Telecom towers and remote sites: Many telecom towers in Bangladesh are located in remote areas. There, maintenance work has to be done quickly and accurately within a limited time. Instruments with a large insulation range and field-supported features will come in handy here.
Industrial Plant & Maintenance: Insulation resistance is checked regularly in factories, building maintenance or switchgear rooms. Low insulation can lead to circuit breakdown or shot origin that’s why having a good insulation tester is essential.
Maintenance Contracts & Safety Audits: Insulation resistance records need to be kept during regular check-ups and safety audits. Units like the Kyoritsu3125B make the job easy and effective.
If you’re looking for a reliable, high-performance insulation tester in the Bangladesh market where a large voltage range, accurate resistance measurement and field-ready design come together then the Kyoritsu3125B is a strong proposition. Of course, take into account the details such as service support, accessories, environmental friendliness as well.
