Single phase AC current and AC/DC voltage injection set. The combination of the ruggedness and ease of use of the VE range with the digital technology of the HEXAN system mean that the SMARTCASE is a good compromise between digital and analogue technologies. The design

of the SMARTCASE means that it is the ideal tool for systematic field testing of over and under voltage, current and frequency relays in addition to wattmeter and impedance relays. The alphanumeric display and menu control clearly indicates the measurements performed.
