Discover why Japanese phase indicators are always popular

Currently, the market has many options from many different brands. Among them, product lines from Japan are often prioritized by technical teams thanks to their compact design, quick operation and suitability for many different working conditions. 

In this article, EMIN introduces to you the popular phase indicator lines from Japanese brands, effectively supporting the work of checking and installing three-phase electrical systems.

Why are Japanese phase indicators always trusted by many people?

It is no coincidence that Japanese phase indicators are so popular. For those who have worked in the field of three-phase electrical installation or inspection, determining the correct phase order is a very important step to avoid the motor from rotating in reverse, causing danger or damaging the equipment. 

When choosing to buy a phase indicator, quality and safety are always the top priorities. And that is also the reason why Japanese brands such as Hioki or Kyoritsu are chosen by many technicians, electricians and ordinary users.

Products from Japan often give quick, clear and easy-to-follow results. Most have indicator lights, warning sounds and simple, easy-to-operate designs. When there is an abnormal signal, the device will respond immediately so you can handle it promptly. 

In addition, the design is also a big plus. Japanese phase indicators are often compact, sturdy, easy to carry when working and can be used in many different environments. Many models have safe insulated clamps, allowing quick operation without having to directly touch the wire.

With these advantages, it is not difficult to understand why devices from Japan are always on the top list of choices for many people when they need an effective, safe and durable phase testing support tool.

Why is it necessary to check the phase order before installation?

In a three-phase electrical system, determining the correct phase sequence is very important. If the sequence is incorrect, the motor may rotate in the opposite direction, causing danger to the operator or damage to the equipment. Many automatic control systems will also not work if the phase is reversed.

Some motors that rotate in the wrong direction also cause vibration, jamming or overload. These errors are not easy to detect at first but can cause silent damage in the long run. Not to mention, if the system has been fixed or installed in a difficult-to-reach location, having to disassemble and reassemble due to incorrect phase will be very time-consuming and labor-intensive.

Checking the phase order from the beginning helps technicians feel secure when supplying power, especially in environments with many machines operating at the same time. With a compact support device such as a phase indicator, you can perform this step quickly, limit risks and ensure the device operates in the right direction from the first time.

What is different about Japanese phase indicator?

Phase measuring devices from Japan often score points thanks to their compact design, quick operation and easy-to-read results. Most models clearly display the phase status with indicator lights or sounds, helping users to immediately recognize if there is a problem. 

Some models also allow testing without directly touching the wire core, suitable for working in environments with limited contact. In addition, high finishing, durable materials and stable operation in many conditions are also reasons why many technicians trust devices from Japan.

Which Japanese phase indicator model should I choose?

The Japanese phase sequence measuring machines are quite diverse, meeting many different needs. Below are some models that are highly appreciated and trusted by many people thanks to their easy-to-operate design, stability in use and convenience in actual work.

Kyoritsu 8031 ​​Phase Indicator

This is one of Kyoritsu's most popular models. The device supports phase sequence testing with direct contact capability, giving fast and clear results. Kyoritsu 8031 ​​measures voltages in the range of 110 to 600V AC, suitable for 50-60Hz frequency. 

The device can also operate continuously with voltages above 500V for about 5 minutes. Users can also monitor phase status via the screen and easily check three-phase connection diagrams. 

With a compact, sturdy design and crocodile clip included, this device is suitable for many different measurement situations, especially limiting collisions that affect the device's connector.

Kyoritsu 8035 Phase Indicator

Also a product of the Kyoritsu line, the 8035 model is widely used in checking the phase wire order in three-phase motor systems. This device helps to determine the correct phase order from the beginning to avoid the motor rotating in the wrong direction.

The strength of the Kyoritsu 8035 is the safe clamp head, which can be used with wires from 2.4 to 30mm. The machine uses a colored LED system and an audible alarm to help users distinguish the phase order easily, even in low light conditions.

This device is commonly used in manufacturing plants, electrical system maintenance areas, or electrically operated machinery installation jobs.

Hioki PD 3129-10 Phase Indicator 

Hioki PD 3129-10 is one of the phase indicator models from Japan that is trusted by many electrical engineers. This product operates on the principle of magnetic induction, allowing the measurement of phase sequence without directly touching the conductor core.

Thanks to that, the inspection becomes safer and more convenient, especially when working in high voltage environments or insulated wiring systems. This device can detect phase through the insulation layer without using metal clamps like conventional models. This is an outstanding advantage, helping to limit risks and increase safety during installation or maintenance.

Hioki PD 3129-10 works well in the voltage range from 100V AC, with a frequency from 45 to 66Hz. The machine is equipped with a clear warning sound, along with a large clamp head for quick and secure operation, even when the working space is limited. 

The product is often used in factories, large buildings, or areas with complex three-phase electrical systems, where high safety is required in testing and monitoring.
