PD-RD300A (PowerPD)

Diagnostic system for circuit breakers encapsulated by electromagnetic waves.

PD-RD300A is a diagnostic system for enclosed switchgear (MCSG).

PD-RD300A detects electromagnetic waves when equipment insulation is altered.

PD-RD300A measures the degree of damage to switching devices, anticipating its failure.

This advanced system allows power station engineers and maintenance coordinators to maintain continuous monitoring of electrical equipment.


  • The PD-RD300A, together with a PD-RM (MUX module) can cover up to 16 encapsulated electrical equipment, thus reducing the initial cost of the system;
  • The analyzed frequency range is 10-100 Mhz. The strongest signal is measured (partial discharge), and the data are obtained by the pulse counting method..
