Catalog number: 103220
Rated tester voltage: 245 kV
The tester is designed for use in an electrical network with a nominal voltage of 220 kV.
This type of testers is used for medium voltage detection with a frequency of 50 Hz on electrical equipment. Voltage presence on a contact point is signalized by optical and sound signal. The sound signal is generated by piezoceramic sounder with shrill fluctuating tone. The optical signaling consist of two flashing bright red LEDs. Proper functioning of the tester including the condition of its power supply cells is controlled by a testing button. While pressed, the tester must deliver both, an optical and sound signal. The tester is equipped by built-in electrical circuit permanently monitoring the condition of power supply cells. If their voltage drops below the limit set, the circuit automatically blocks the optical and sound signaling. Subsequently, the tester does not deliver any signal when the testing button is pressed. In this case it is necessary to replace the power supply cells.
The testers are designed for use in outdoor environments without restrictions (also in rain, snow and fog) and indoors with humid environments. The testers are designed for climate class normal from -25 ° C to + 55 ° C.
The testers are supplied in casing.
