87T — Transformer differential relay.

Compares high-side and low-side currents of a transformer. Trips when the differential current |I_H - I_L/ratio| exceeds the restraint characteristic slope × I_restraint + I_pickup.

Fields

slope1: f64

Slope 1 of restraint characteristic (typical 0.2–0.3).

slope2: f64

Slope 2 (high-current region, typical 0.6–0.8).

i_pickup: f64

Minimum pickup current (pu).

harmonic_restraint: f64

2nd harmonic blocking ratio (typical 0.15–0.20). Trip blocked if 2nd-harmonic content > ratio × fundamental.

from_bus: u32

High-side bus number.

to_bus: u32

Low-side bus number.

circuit: String

Circuit identifier.

turns_ratio: f64

Turns ratio (high-side / low-side rated voltage).

tf: f64

Measurement filter time constant (s). Default: 0.01 (10ms).
