PUSH Electrical PS-YC115 On-Load Tap-Changer Tester

Maintenance Testing: OLTC testers are used by utility companies, maintenance contractors, and power system operators to perform routine diagnostic tests on tap-changers installed in power transformers. These tests help identify potential issues or defects in the tap-changer mechanism and associated components, allowing for proactive maintenance and repair actions.

Commissioning: During the commissioning process of power transformers, OLTC testers are employed to verify the proper operation and alignment of tap-changers with the transformer windings. This ensures that the tap-changer functions correctly and switches between tap positions smoothly without causing interruptions or voltage fluctuations in the electrical network.

Troubleshooting: When tap-changer malfunctions or operational problems occur, OLTC testers are used to diagnose the root cause of the issue by conducting comprehensive electrical tests and performance evaluations. This helps troubleshooting teams quickly identify and rectify any faults or abnormalities in the tap-changer mechanism, minimizing downtime and service disruptions.

Electrical Testing: OLTC testers perform a range of electrical tests, including winding resistance measurement, insulation resistance measurement, voltage regulation tests, and dynamic resistance measurements during tap-changing operations.

Control Interface: These testers typically feature user-friendly interfaces with intuitive controls and graphical displays, allowing operators to easily configure test parameters, monitor test progress, and analyze test results in real-time.

Safety Features: OLTC testers incorporate safety mechanisms such as interlocking systems, overload protection, and emergency stop buttons to ensure operator safety during testing procedures and prevent damage to the tap-changer and associated equipment.

Data Logging and Analysis: Advanced OLTC testers are equipped with data logging capabilities to record test data, waveform captures, and event logs for further analysis and reporting. This facilitates comprehensive assessment and documentation of tap-changer performance over time.

Preventive Maintenance: Regular testing with OLTC testers helps identify potential issues or deteriorations in tap-changer condition before they escalate into major failures, enabling proactive maintenance and extending the service life of power transformers.

Enhanced Reliability: By verifying the proper operation and alignment of tap-changers, OLTC testers contribute to the overall reliability and stability of power transmission and distribution systems, reducing the risk of unplanned outages and equipment damage.

Regulatory Compliance: Compliance with industry standards and regulatory requirements is ensured through periodic testing and documentation of tap-changer performance using OLTC testers, demonstrating adherence to best practices in power system maintenance and operation.
