ABB 87TS50R1214 GKWE 857800R1214 protective relay card

ABB 87TS50R1214 GKWE 857800R1214 protective relay card

ABB 87TS50R1214 is a protective relay card mainly used to protect transmission lines and substation equipment in high-voltage power systems.

The following are the main parameters and functions of 87TS50R1214:

Parameters:

Functions: differential protection, overcurrent protection, overfrequency protection, underfrequency protection, zero sequence protection, etc.

Rated voltage: 50/60 Hz, 120V DC

Rated current: 1A or 5A

Rated load: 6VA

Operating temperature: - 40 ° C to+85 ° C

effect:

Differential protection: monitors the current difference between the two ends of the transmission line. When the difference exceeds the set value, the relay acts to cut off the circuit and protect the power equipment from faults.

Overcurrent protection: Monitor the current in the power system. When the current exceeds the set value, the relay acts to cut off the circuit, protecting the power equipment from overcurrent damage.

Overfrequency protection: monitors the frequency in the power system. When the frequency exceeds the set value, the relay acts to cut off the circuit, protecting the power equipment from abnormal frequency effects.

Under frequency protection: monitors the frequency in the power system. When the frequency is lower than the set value, the relay acts to cut off the circuit, protecting the power equipment from abnormal frequency effects.

Zero sequence protection: Monitor the zero sequence current in the power system. When the zero sequence current exceeds the set value, the relay acts to cut off the circuit and protect the power equipment from damage caused by the zero sequence current.
