Seaward PH3 High Voltage Proving Unit

Seaward PH3 High Voltage Proving Unit

The Seaward PH3 High Voltage Proving Unit provides a simple way to check that high voltage indicators are working correctly before and after use. It delivers a stable DC output and helps users confirm the operation of compatible voltage detection equipment. Its compact design also makes it easy to carry between testing locations.

Built for field use, the Seaward PH3 High Voltage Proving Unit is battery powered and highly portable. Users can quickly verify the performance of high voltage indicators without needing an external power source. As a result, routine safety checks can be completed efficiently.

Reliable High Voltage Verification

Designed for use with high voltage potential indicators and phasing rods fitted with domed contact electrodes, this unit produces a nominal 1500V DC proving output. The integrated neon indicator provides a clear visual confirmation when the output voltage is active. This allows users to confirm functionality with confidence.

In addition, the Seaward PH3 High Voltage Proving Unit features dedicated test terminals that include a contact electrode and test post. These connections support straightforward proving procedures and help maintain consistent testing practices. The compact housing remains practical for both workshop and site environments.

Portable Safety Testing Solution

The Seaward PH3 High Voltage Proving Unit is suitable for use with compatible Seaward voltage indicators including the KD1E, KD1E/KAD, KD1E/22, KD1E/15D and KD1E/33D models. Its lightweight construction helps reduce the burden of carrying test equipment while working across multiple locations. This makes it well suited to regular inspection routines.

Two different set types are available to suit varying application requirements. Furthermore, compliance with IEC 61010-1 helps ensure the unit meets recognised electrical safety standards. Combined with its reliable proving output, the unit offers a practical solution for confirming indicator operation before and after use.
