Overvoltage Protector Tester

HMBP-40 overvoltage protector tester is widely used for power frequency discharge voltage testing of various electrical equipment, especially for zinc oxide overvoltage protectors with gaps (also known as lightning arresters or TBPs). Unique effect. The tester uses a new type of special circuit to monitor the test voltage waveform, and at the same time collect the discharge pulse signal of the current loop, automatically judge the gap discharge, lock the voltage peak value at the moment of storage, and send out an audible alarm signal to remind the tester , And quickly cut off the test power supply to protect the test product and test equipment from overcurrent damage. The tester integrates power frequency high voltage power supply, measurement and control system, concentrated in an engineering plastic box, is small in size, light in weight, shockproof and drop resistant, easy to operate and easy to carry.

1. Output voltage 0-30KV (effective value); output current 0-25mA

2. Detecting discharge method: waveform detection and Fourier transformation method

3. Accuracy: Voltage: ±(reading×2%+0.1) Current: ±(reading×2%+0.1)

4. High pressure cut-off time: less than 0.2 seconds

5. Voltage resolution: 0.001KV Current resolution: 0.001mA

6. Input power: 180V～270VAC, 50Hz/60Hz±1%, power supply from mains or generator

7. Computer interface: standard RS232 interface 8. Printer: thermal micro printer

9. Ambient temperature: -10℃～50℃ Relative humidity: <90%

1. The instrument uses waveform detection and Fourier transformation to monitor the discharge current at all times. When the discharge current is monitored, it immediately records the high voltage at the moment and cuts off the high voltage power supply within 0.2s. The test result has high accuracy, which is convenient for automatic measurement.

2. Full touch LCD screen, super large graphic operation interface, every process is very clear and clear. Operators can use it without additional professional training. The whole process of testing can be completed with a light touch.

3. The instrument is easy to operate, and the data measurement is automatically completed under the control of the microprocessor. No manual intervention is required.

4. All-in-one model with built-in high-voltage power supply, which is convenient for on-site testing and reduces on-site wiring.

5. High-voltage protection: The test product can be short-circuited, broken down or high-voltage current fluctuations, and the output can be cut off at a high speed in a short-circuit mode.

6. Low voltage protection: wrong connection of 380V, power supply fluctuation or sudden power failure, start protection, will not cause over voltage.

7. Misoperation prevention: real-time monitoring of voltage and current; clear high/low voltage of the terminal; slow boost, fast drop, and audible alarm.

8. Seismic performance: The instrument adopts a unique anti-seismic design, which can withstａnd strong long-distance transportation vibration and bumps without being damaged.

9. High-voltage cable: high-voltage resistant insulated wire, but for accurate measurement, please use it in the air.
