Safe discharge rods allow technicians to conduct the safe damp discharge of the residual charge on an electrical cable or piece of equipment by limiting the discharge current. The instruments are used by extensively by electric utility workers when engaged on live-line working on high voltage electric power lines. Safe discharge rods are made of fibre glass strengthened plastic) and include a safety handle with conservatively rated clearance against physical contact with high voltage. Each models features a discharge resistor or encapsulated resistor chains to carry out the “damp” of the current.
Calibrationhouse as part of the Seaward Group benefits from 40 years of experience in design, manufacturing, and calibration of safe discharge rods. The Seaward SDR series of safe discharge rods are suitable for voltages up to 35kV and include a variety of features and accessories to ensure testing is as seamless as possible. The instruments are single pole in construction and include a heavy duty brass clamp to ensure secure and easy connection with earth points.
Owing to the high voltage required as a calibration standard for these devices, onsite calibration is not feasible. Calibrationhouse through a specialised high voltage faraday test cage therefore offers discharge rod calibration services exclusively from its Durham based laboratory. Please contact us to discuss your discharge rod calibration requirements in more detail.
