High Voltage Switch Dynamic Characteristics Tester | VS-5308

Products Details

The VS-5308 integrates timing measurement, travel analysis, speed calculation, coil current testing, coil resistance measurement, and built-in DC control power output in one portable instrument. It is suitable for testing high-voltage switches with multiple contact channels and supports common operating sequences such as opening, closing, O-C, C-O, and O-C-O.

The tester provides a digitally adjustable DC output from 0 to 270 V for breaker operation, helping technicians perform field tests without relying entirely on external control power. With a large backlit LCD, built-in printer, USB data export, and storage for up to 1000 groups of test records, the VS-5308 is practical for substations, switchgear factories, maintenance teams, and power testing service companies.

Product Guide

1. Connect the protective ground wire before making other test connections.
2. Connect the switch contact timing leads according to the required phase and contact arrangement.
3. Select the test mode, such as opening, closing, O-C, C-O, or O-C-O.
4. Connect the travel sensor or speed sensor when travel and speed data are required.
5. Set the operating voltage if the built-in DC output is used.
6. Start the test and allow the instrument to capture timing, waveform, travel, speed, and coil data.
7. Review the results on the LCD screen and print the test record if required.
8. Export saved data through USB for archiving or further report preparation.

For field safety, the protective ground should be connected first and removed last. The operator should also avoid short-circuiting the lockout release output,

9. Includes adjustable energy storage output for breaker motor operation.
10. Supports internal trigger, external trigger, sensor trigger, manual trigger, and current trigger modes.
11. Includes 12 contact timing channels for multi-break switch testing.
12. Stores up to 1000 groups of test data.
13. Supports USB data export and software upgrade.
14. Includes a built-in micro printer for on-site report printing.

Application Scenarios

The VS-5308 is used by power utilities, electrical maintenance companies, switchgear manufacturers, industrial plants, railway power departments, and testing laboratories. It is suitable for evaluating the operating condition of high-voltage switches, especially 35 kV and below vacuum switches with DC 110 V or DC 220 V energy storage mechanisms.

Applications

1. Routine maintenance of high-voltage circuit breakers.
2. Commissioning inspection for vacuum circuit breakers.
3. Mechanical characteristic testing of switchgear before energization.
4. Fault diagnosis for abnormal opening or closing behavior.
5. Factory inspection of medium-voltage switchgear.
6. Field verification after breaker repair or mechanism adjustment.
7. Operation sequence testing for substation switching equipment.

Customer Case

A maintenance team at a 35 kV distribution substation used the VS-5308 during routine breaker inspection. One feeder breaker showed unstable closing behavior during operation. By testing closing time, inter-phase synchronism, bounce waveform, coil current, and travel data, the team identified abnormal mechanical movement caused by mechanism wear and insufficient adjustment.

After servicing the mechanism and repeating the test, the closing synchronism and travel waveform returned to the expected range. The stored test records and printed reports were used as maintenance documentation for the substation archive.
