Over- / Under- / Reverse- Power WTG7100
Relays for protective functions requiring a real measure of the active or reactive power (and power direction).
Advantages:
- Detects unbalanced power in the case of 3 wire three phase networks, measured by the two wattmeter method.
- Directional stability; active power relay totally unaffected by current and voltage harmonics.
- Continuously adjustable operating thresholds.
- Low burden on current and voltage transformers.
Six models are available :
Reverse power (active) ANSI 32RP:
