The new S1-552 and S1-1052 insulation resistance testers from Megger are designed to assist the user with the testing and maintenance of high-voltage equipment. Each instrument’s control panel is ...

Voltage testers check for difference in potential in electrical circuits. Measurement type and measurement range are the most important parameters to consider. There are three main measurement types: ...

Proper calibration of this test equipment is crucial to meeting the strict performance requirements of many high-voltage systems. Calibration results often need to comply with national or ...

Voltage tester, tick-tracer, glow-tip, non-contact voltage tester... whatever. Same thing. I call it a voltage sniffer, but the technical name for this device is a capacitive voltage sensor. That's a ...

AVTs help reduce the risk of exposure to electrical hazards and improve worker safety by automating and simplifying the process of verifying the absence of voltage. The importance of creating a safe ...

What is partial discharge? Methods for measuring PD. How PD impacts high-voltage cables. Partial discharge (PD) is evidence of a degrading insulation system, which could trigger costly repairs and ...

Hastings new voltage tester ensures safety for line workers by giving them the voltage information they need to make the right decisions on the job. This live tester, non-contact voltage detector uses ...

Measuring rise time for a power source. Voltage vs. time signals measurements via a scope. A practical setup for battery testing. I was recently asked a question about a dc power supply, aka a voltage ...

For over a decade, thousands of users have deployed permanent electrical safety devices (PESDs) to reduce the risks in isolating electrical energy. This elegantly simple innovation increases the ...
