Phasing sticks are specialised test instruments that allow technicians to determine if two electrical conductors are in-phase with each other, measure phase to phase voltage, compare phase to phase voltage or test between phase and earth connections. Sometimes known as phasing rods, phase comparators or hot-sticks these devices are generally large in construction but lightweight enough to be moved between a variety of test points during the course of a technicians day. Phasing sticks usually form part of a larger test kit comprising digital voltage indicators and phasing rods with a detachable earth lead. The digital voltage indicator can be used by technicians separately to the phasing rod as a voltage stick or voltmeter.
Calibrationhouse as part of the Seaward Group benefits from 40 years of experience in design, manufacturing, and calibration of phasing sticks. The Seaward PR11, PR15D and PR33D are used abundantly in industry for testing of electrical switchgear systems and several other HV applications within the utility and electrical engineering sectors. These phasing sticks can be used on earthed neutral systems up to 33KV and provided as standard with a proving unit for regular verification purposes.
The high voltage needed to calibrate phasing sticks means that onsite calibration of these instruments is not possible. Calibrationhouse therefore only offers phasing stick calibration services from its state of the art test facility in County Durham. Our high voltage faraday cage and years of testing knowledge ensures phasing stick calibration is performed to the highest possible standard every time. We recommend a minimum period of 1 year between calibration of Seaward and other high voltage phasing sticks, heavy use equipment may require more regular checks.
