Masensa anofanirwa kutevedzera zvinodiwa neIEC61010-1. Masensa anofanirwa kuiswa mumidziyo yemagetsi kana yemagetsi inosangana nezvinodiwa zvekushandisa uye zvinodiwa zvekuchengetedza zvichienderana nemirairo yekushandisa.
- Chenjerera. Chenjerera kana paine zvinhu zvinovhundutsa.
Kana sensor iri kushanda, zvimwe zvikamu zvinogona kukanganiswa nemagetsi ane njodzi (semuenzaniso primary busbar, power supply), uye kuregeredza izvi kuchaita kuti pave nekukuvara nenjodzi huru. Sensor iyi mudziyo wakavakirwa mukati, uye chikamu chayo chinofambisa magetsi chinofanira kuvimbiswa kuti hachibatwi nenyika yekunze mushure mekuiswa. Chivharo chekudzivirira kana chifukidziro chekudzivirira chinogona kuwedzerwa kana zvichidikanwa. Simba guru rinofanira kukwanisa kuvharwa.
