Product Details

The Westminister Detector range of Discharge Earthing Rods are used for the removal of electrostatic charge from disconnected circuits, prior to undertaking maintenance work.

Manufactured from 1.2metre-long lightweight insulating tubing and fitted with a discharging hook. The connection to earth is facilitated by a 4 metre-long earth cable with earthing clips. Models are available with a discharge limiting resistor for use upon capacitors.

Instructions for Discharge Rods with discharge limiting resistor

Ensure that the discharge rod to be used has a value resistor appropriate for the circuit to be tested. Either 15kV type or 35kV type.

Connect the cable clamp to a known earthing point and apply the end hook to the circuit ensuring that the discharge rod is at all times held below the hand shield/limit ring.

The static charge will be removed through the resistor in the rod at a controlled rate.

After at least 5 seconds, remove the end hook and the apply the lower hook to the circuit. This is directly connected to the earthing cable and its earth clamp which will remove any remaining charge from the circuit.

Instructions for Discharge Rod without discharge limiting resistor

Connect the cable clamp to a known earthing point and apply the end hook to the circuit ensuring that the discharge rod is at all times held below the hand shield/limit ring.

After a minimum of 1 second, remove the discharge rod. The static charge will be removed directly through the earthing cable and cable earth clamp.

General Product Instructions

Before using the discharge rod, the circuit should be tested using an appropriate voltage detector to verify that the circuit has been disconnected. These are also available from our Westminster Detector range.

Ensure that the discharge rod that is to be used has an insulation level satisfactory for the circuit to be tested. These instructions should be read in conjunction with site safety instructions and PPE should be used in accordance with theses. Ensure that all site safety procedures are observed for access, safe use and removal from site.
