Battery testing equipment

Understanding the Importance of Battery Testing

Research on battery testing shows that a battery cell’s internal resistance gradually increases with both age and discharge history. Since batteries are frequently used as backup systems in power supply, especially in UPS systems, their operational readiness becomes crucial in the event of a power outage. Therefore, it’s essential that the battery consistently delivers the required capacity to support such systems effectively.

Moreover, regulations mandate regular battery testing, particularly for safety-critical systems backed by emergency power sources. According to VDE standards, these tests must always be documented and thus remain verifiable at any time.

The Necessity of Regular Battery Testing

As a result, regular battery tests are mandatory. These tests assess the battery’s storage capacity and performance under load over a specific period. Notably, these tests are conducted in the batteries’ current operational state, as outlined in DIN EN 60896-11. This ensures that the assessment reflects the battery’s actual performance conditions.

The Role of WGM Support in Battery Diagnostics

Introduction to the BTA 200 Battery Condition Analyzer

The BTA 200 Battery Condition Analyzer is an advanced device specifically designed for the precise monitoring of battery health. Stationary batteries, especially those used in critical applications such as emergency power supply systems, benefit greatly from this device. The BTA 200 combines modern technologies to ensure that batteries function optimally.

Measuring Internal Resistance

One of the key functions of the BTA 200 is the measurement of internal resistance in batteries. This measurement is crucial as it assesses the condition of the battery electrodes and the stability of the cell structure. In emergency power systems, where a stable energy supply is essential, internal resistance measurement plays a central role. It helps to detect potential issues early, allowing for corrective measures before failures occur.

Conductivity Testing for Improved Efficiency

In addition to internal resistance measurement, the BTA 200 can also test the conductivity of the battery. This function enables the evaluation of the battery’s electrical performance. A good conductivity rating ensures that the battery operates efficiently and provides a reliable energy supply. This is particularly important since consistent performance is critical for the efficiency of energy systems that rely on stationary batteries.

Connection Cable Testing for Secure Connections

Another important feature of the BTA 200 is its connection cable testing. The device checks whether the battery’s cable connections are functioning correctly. Poor connections can lead to voltage drops and disrupt energy transfer. Such issues could result in significant failures in critical applications. The BTA 200 ensures that the connection cables do not cause power losses, improving the overall reliability.

AC Signal Discharge for More Accurate Measurements

Using the advanced method of AC signal discharge, the BTA 200 can measure the battery’s internal resistance even more accurately. This method allows for the assessment of resistance under varying operational conditions. As a result, more precise measurements are obtained, particularly for batteries subjected to different loads.

User-Friendly Operation

Another outstanding feature of the BTA 200 is its user-friendly interface. The device is equipped with a TFT touchscreen as well as a keypad, making it easier to operate. Thanks to this intuitive interface, it is simple to navigate the various functions and perform tests. This greatly facilitates monitoring and testing, for instance, in centralized battery systems.

Data Management and Analysis for Informed Decisions

Finally, the BTA 200 offers comprehensive data management and analysis capabilities. Specialized software enables efficient management of all collected data. These can be analyzed and reports can be generated to support informed decisions in battery management. This helps to optimize the performance of battery systems and enhance their reliability.

Conclusion

In summary, the BTA 200 Battery Condition Analyzer is a versatile and powerful device. It offers a range of features specifically tailored for the analysis and monitoring of stationary batteries. With its precise measurements, user-friendly interface, and efficient data analysis, the BTA 200 is an essential tool for battery management in critical systems such as emergency power supply, telecommunications networks, and data centers.

DC Ground Fault | GFL1515 | Battery Ground Fault

Battery Ground Fault | Battery Check
GFL1515: Essential for Detecting DC Ground Faults in DC Systems

The GFL1515 is an essential measuring device for detecting DC ground faults in various DC systems. This GFL1515 Detector is crucial for identifying faulty grounding, especially where electrical cables are damaged or show leakage to the ground.

Fault Detection Through Signal Injection

The GFL1515 detects unintentional DC ground faults by injecting a low-frequency signal into the faulted polarity. Using current clamps and a portable receiver, operators can follow this signal to pinpoint the physical location of the DC ground fault.

Online Measurements with High Voltage Tolerance

The GFL1515 enables measurements even in online DC systems. While the device’s output current remains low, its output voltage can reach up to 1000V, allowing it to function safely without interference. Per the NERC PRC 002-6 standard, the battery and DC power system must be checked for unintentional grounding every four months. If a ground fault is found, the GFL1515 allows for precise fault localization without disconnecting the live circuit.

Method for Fault Localization

The GFL1515 uses several methods to locate faults accurately, based on these principles:

Signal Generator and Return Circuit

The signal generator connects to the DC system with two test leads, injecting a low-frequency current signal. This signal flows through the circuit, exits at the faulted grounding point, and finally returns to the generator. This return circuit assists in signal tracing in the next step.

Signal Receiver for Directional Tracking

The signal receiver tracks the signal’s direction, which always points toward the fault. Using one clamp on two busbars, or two clamps on separate busbars, the device works efficiently with strong anti-interference capability, even in online systems.

Signal Strength and Phase Angle Changes

The strength and phase angle of the signal change significantly before and after the grounding fault. These changes help pinpoint the exact fault location with accuracy.
