PD-300/500 Family
All different types of PD-300 and PD-500 protective relays, make up a family of differential protections for 2 and 3 winding transformers respectively and generators. They incorporate Protection, control, and oscillograph recording functions.
There are three different models of differential protection relays:
VOLTAGE REGULATORS
All different models of voltage regulators make up a family for the power transformers’ voltage regulation, actuating upon the tap changer of those transformers, using the measured voltage and current values.
There are three different models:
- TCP/RM: Single-phase regulator
- TCP/RT: Three-phase regulator
- TCP/RC: Three-phase regulator with reactive compensation
