SEW 277 HP high-voltage detector

The SEW model 277 HP is a non-contact, high-voltage detector suitable for voltages from 50 V to 132 kV via two operating ranges, 50 to 1500 V and 1500 V to 132 kV, selectable by means of range buttons. The principle of operation is based on capacitive voltage detection of AC voltage and the presence of voltage is indicated by means of blue LEDs, positioned next to the instrument’s handle, which is fitted with a sunrise connector suitable for attaching to a hot stick.

Two hot stick models are available for use with the SEW 277HP non-contact, high-voltage detector. The SEW HS-175 telescopic hot stick provides for insulation safety at 100 kV per 30 cm length (5 min) and is available with up to nine sections providing a total reach length of 12.09 m. A disconnection hook is provided as standard, as is a universal sunrise head.
