KYORITSU CURRENT & VOLTAGE LOGGER KEW 5020

Description

A Comprehensive Solution for Power Analysis

The device described is an advanced data logger with 3 channel inputs, a standout feature that allows it to simultaneously record leakage current, load current, and voltage. This triple-input capability provides a holistic view of an electrical system’s performance, making it an indispensable tool for a wide range of professionals. By capturing these three critical parameters at the same time, the logger allows users to correlate data and uncover complex issues that would be missed by devices that measure only one or two parameters. This is essential for comprehensive diagnostics, allowing technicians to not only see that a problem exists but also to understand its cause and effect within the system. The device’s robust design and compact size make it highly versatile, suitable for use in industrial, commercial, and residential environments.

The logger’s technical specifications highlight its precision and reliability. It uses a True RMS measuring method, which is crucial for accurately measuring the complex, non-sinusoidal waveforms found in modern electrical systems. This ensures that the data recorded is an accurate representation of the actual conditions, which is vital for making sound engineering decisions. To further enhance accuracy, the logger features a Lowpass Filter that effectively removes harmonics from the signal. This is especially important when measuring leakage current, as harmonics can lead to inaccurate readings and misdiagnoses. The device also has a large storage capacity, capable of holding up to 60,000 data points in its non-volatile memory. This generous memory allows for long-term data logging, enabling the user to conduct detailed studies over days or weeks without the need for frequent data downloads.

Advanced Recording and Power Quality Analysis

This logger is equipped with multiple recording modes, offering flexibility for different diagnostic needs. The Normal Recording Mode is perfect for general monitoring and trend analysis, while the Trigger Recording Mode is designed to capture specific events. In trigger mode, the device can be set to start recording only when a preset current or voltage value is exceeded, which is invaluable for diagnosing intermittent faults that are hard to catch with continuous logging. The Capture Recording Mode takes this a step further by capturing the actual waveform of an event, providing a detailed visual representation that can be analyzed to determine the exact nature of the fault.

Beyond basic measurements, this device excels at Power Quality analysis. The ability to record voltage alongside current provides the necessary data to assess power quality issues like voltage sags, swells, and momentary interruptions. By analyzing this data, engineers can identify the root cause of sensitive equipment malfunctions or system instability. The logger’s continuous measuring time of approximately 10 days on a single set of alkaline batteries makes it perfect for long-term power quality studies, ensuring that even infrequent events are captured. An integrated LED flickers when a preset value is exceeded, providing an immediate visual alert of a significant event.

Essential Applications in Industry and Commerce

This versatile logger has a wide array of applications that are essential for professionals in various fields. For preventive maintenance, it is an indispensable tool for monitoring the health of electrical insulation. By regularly logging leakage current, technicians can track gradual degradation and identify potential faults before they lead to a system failure, a fire, or an electrical shock hazard. This proactive approach saves time and money by preventing unplanned downtime and costly repairs. The logger’s ability to monitor load current simultaneously also allows for the assessment of equipment efficiency, helping to identify motors or other loads that are drawing excessive current and may need servicing or replacement.

Another critical application is electrical troubleshooting. Many problems, such as flickering lights or a circuit breaker that trips randomly, are intermittent and can be extremely difficult to diagnose. By deploying the logger, technicians can capture these fleeting events, providing the data needed to pinpoint the cause. For example, a sudden drop in voltage captured by the logger might indicate a momentary fault in the power grid or a large load starting on the same circuit. The CALL function allows for quick confirmation of recorded data on-site, a practical feature for busy technicians.

The device is also perfect for energy audits and load profiling. By recording voltage and current over an extended period, it provides a detailed picture of energy consumption patterns. This data can be used to identify peak demand times, analyze how different loads contribute to overall consumption, and implement strategies for energy savings. This is particularly useful for facility managers and energy consultants who need to make data-driven decisions to reduce operating costs and improve the efficiency of their electrical systems. The logger’s robust performance, combined with its user-friendly software, makes it a powerful tool for optimizing energy usage.

Seamless Data Analysis and Management

The provided specifications highlight the importance of a streamlined workflow, which is where the KEW LOG Soft2 PC software plays a critical role. After a recording session, users can connect the logger to a PC via the included USB cable (7148) to download the data. The software provides a comprehensive interface for analyzing the recorded data, presenting it in clear graphs and reports. This allows for quick and efficient interpretation of trends, anomalies, and specific events. The software also enables the user to configure the logger’s settings remotely, such as the recording mode and intervals, saving time and effort during setup.

The logger’s design is also optimized for convenience and durability. Its compact dimensions and light weight (approx. 265g) make it highly portable, and the included carrying case (9118) ensures it is well-protected during transport. The device features an auto-power-off function to conserve battery life, which is automatically disabled during a recording to prevent accidental data loss. This thoughtful design, combined with its long battery life, makes it a reliable and practical tool for extended fieldwork. The battery power indicator, with its 4-level display, keeps the user informed of the remaining power, ensuring that no recording session is cut short unexpectedly.

The Power of Simultaneous Measurement

The true strength of this device lies in its ability to conduct simultaneous measurements across multiple channels. For example, in a three-phase system, a technician can use one channel to measure leakage current in the ground wire, a second to measure the total load current in one of the phases, and a third to measure the voltage. This allows for a direct correlation between these parameters. If a voltage sag is recorded, the technician can immediately see how it affects the load current and if it causes a spike in leakage current. This kind of correlated data is invaluable for diagnosing complex power issues that are often interconnected.

The logger’s robust design and compliance with standards like IEC 61010-1 CAT Ⅲ 300V demonstrate its suitability for demanding professional applications. This safety rating ensures that the device can be used safely in environments with high transient overvoltages. The variety of optional accessories, including different types of clamp and flexible sensors, allows the user to customize the logger for specific measurement needs, from low-current leakage to high-current loads up to 1000A. The availability of a voltage sensor (8309) further enhances its versatility, solidifying its position as a go-to tool for a wide range of electrical analysis tasks.
