DEHN’s PHV phase comparators have SABS approval and meet the requirements of SANS/IEC 61481 standards. The two-pole devices offer safe and reliable operation while testing for in-phase conditions in three-phase electrical systems. They are suitable for voltages up to 36 kV/50 Hz.
Used in contact with the parts to be tested, the PHV phase comparator is insensitive to magnetic and electrical interference. Various colour coded test prods are available for select voltages, with a simple bayonet connection that ensures easy coupling to the test unit. Compact prods are ideal for use in areas where space is limited, while the standard versions are suited for areas where larger span and separation is required. Test prods with a 90° angle are available for testing in switchgear where the axis of the bushing is mounted in a vertical plane.
The PHV phase comparator has distinctive red rings on both test prods that mark the end of the insulating sections in the direction of the operating head/indicator, providing increased protection for the operator.
