It is used as an ATS device in 0.4 - 150 kV networks. Optimized to perform the ATS function in 0.4 kV networks.
Description
Performs the following functions:
Provides control and measurement of the following quantities:
- three currents: one phase input 1, one phase input 2, one phase intersection;
- three phase/line voltage input 1;
- three phase/line voltages input 2;
- mains frequency on both inputs;
- angles between all currents and voltages.
Relay protection functions:
- four-stage undervoltage protection with AND or OR triggering,
- four-stage overvoltage protection with AND or OR triggering.
Automation and control functions:
- automatic switching on of the reserve (ATS) with the ability to work not only for lowering, but also for increasing voltage;
- Automatic Normal Mode Restore (AVHR)
- control of switches of inputs and SV,
- monitoring the switching resource of the circuit breaker,
- phasing control.
