Mfumo wa Ufuatiliaji wa Joto la Fiber Optic kwa Vibadilishaji vya Aina Kavu

A major power facility utilizes high-voltage dry type transformers as core power supply equipment. Since dry type transformers rely on air convection for cooling, accurate monitoring of winding hot spot temperatures proved challenging. Traditional PT100 sensors cannot directly contact high-voltage windings, creating temperature measurement blind spots and potential safety risks.

Our Solution

We deployed a Mfumo wa Ufuatiliaji wa Joto la Fiber Optic to achieve precise temperature control through the following implementation:

Kwa nini Chagua Ufuatiliaji wa Fiber Optic?

Advantages Over Traditional Methods

Direct Hot Spot Measurement: Unlike PT100 sensors that measure external temperatures, fiber optic sensors can be embedded directly into windings for true hot spot monitoring.

No Electrical Interference: Being non-conductive, fiber optic sensors eliminate concerns about electrical breakdown, grounding issues, or signal interference in high-voltage environments.

Explosion-Proof Design: With no electrical components at the sensing point, fiber optic systems are intrinsically safe for use in hazardous locations.

Lightning Protection: Non-metallic fiber optic cables are immune to lightning strikes and electrical surges that can damage conventional wiring.

Maintenance-Free Operation: Solid-state sensing technology with no moving parts ensures decades of reliable operation without calibration or replacement.
