- Product Introduction
Manufactured by Jinneng Electric Power Technology (Hubei) Co., Ltd., our Detuned Harmonic Filter Reactors are built using premium, low-loss silicon steel cores, high-grade winding insulation, and precision engineering techniques. Featuring high-purity copper or aluminum foil windings, they deliver exceptional performance, minimal temperature rise during continuous duty, and long-term operating reliability.
As an established OEM partner for leading global brands, our quality is industry-recognized and widely praised by end-users. With current linearity up to 1.8 times, low power loss, and a strict relative inductance deviation within ±2%, our reactors ensure excellent phase-to-phase consistency in voltage and current. Detuned Harmonic Filter Reactors effectively attenuate harmonics and safeguard power distribution equipment-making them a cost-effective, high-reliability alternative to European tier-1 brands for demanding projects.

Core Index
Test result of 2 Detuned harmonic filter reactors in our production line as example:
Three-Phase Reactance / Inductance Balance:
This is the most critical quality index of the reactor, which directly determines three-phase current balance, temperature rise uniformity and filtering effect.
| Index | Reactor No.1 (Left) | Reactor No.2 (Right) | National/Industry Standard Requirement | Evaluation |
|---|---|---|---|---|
| Three-phase Reactance (Ω) | A: 0.5546 / B: 0.5622 / C: 0.5526 | A: 0.5476 / B: 0.5558 / C: 0.5452 | Deviation of each phase from the average value ≤ ±2% | Both units far exceed the standard |
| Maximum Relative Reactance Deviation | 1.37% | 1.53% | ≤ ±2% | No.1 performs better, and No.2 is also excellent |
| Three-phase Inductance (mH) | A: 1.7657 / B: 1.7900 / C: 1.7595 | A: 1.7441 / B: 1.7702 / C: 1.7365 | Deviation of each phase from the average value ≤ ±2% | Excellent consistency for both units |
| Maximum Relative Inductance Deviation | 1.37% | 1.53% | ≤ ±2% | Both are far below the national standard limit |
Active Power Loss
Lower power loss means less heat generation, longer service life and higher energy efficiency.
| Index | Reactor No.1 (Left) | Reactor No.2 (Right) | Conventional Industry Level | Evaluation |
|---|---|---|---|---|
| Total Three-Phase Loss ΣP | 0.1311 kW (131.1W) | 0.1382 kW (138.2W) | 150W ~ 200W | Both reach high-quality low-loss level |
| Maximum Single-Phase Loss | Phase B: 0.0443kW (44.3W) | Phase B: 0.0505kW (50.5W) | 60W ~ 70W | Superior loss control performance |
Voltage / Current Consistency
The parameters of the two products are highly similar, indicating that the production process and material selection are consistent.
| Reactor No.1 (Left) | Reactor No.2 (Right) | Evaluation | |
|---|---|---|---|
| Three-phase Voltage (V) | A: 19.275 / B: 19.550 / C: 19.325 | A: 19.169 / B: 19.429 / C: 19.185 | Highly balanced three-phase voltage with no obvious deviation |
| Three-phase Current (A) | A: 34.755 / B: 34.771 / C: 34.966 | A: 35.004 / B: 34.956 / C: 35.188 | Nearly identical three-phase current, further confirming excellent electrical symmetry |
Conclusion
- Both reactors are high-quality qualified products. All core indicators (three-phase balance and power loss) fully exceed national standard requirements with superior overall performance.
- Stable quality control of the same batch. The two products present highly consistent parameters, which proves unified production processes and material selection with minor individual differences.
- High reliability for long-term operation. Low power loss and excellent three-phase balance ensure uniform heat generation and no unbalanced load during operation, extending service life and making the products suitable for long-term continuous operation.
