Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

An initial sign of a failing Current Transformer might be inconsistent or fluctuating voltage readings on the generator control panel. If left unaddressed, this can lead to the generator shutting down unexpectedly or failing to meet load demands. The worst consequence is potential damage to connected equipment due to unstable power output.

Installation Tip

Ensure all power sources are completely disconnected and locked out before attempting installation to prevent electrical shock. Double-check that the primary and secondary wiring connections are made to the correct terminals as per the service manual.

Service Note

Inspect the generator's voltage regulator and wiring harness for any signs of damage or wear when replacing the Current Transformer.
