Lift the user appl ication stability comprehensive protection function
Learning function:
In addition to the Fourier algorithm, GROCH original smart Fourier algorithm, can automatically learn the grid environment and system impedance, avoid system oscillation effectively, make the system to achieve the most stable state of compensation.
Harmonic monitoring:
The process of load change, if appear resonance, APF self judgment and exit system, alarm at the same time, to avoid failure.
Temperature monitoring:
Real-time monitoring of ABC three-phase heating device (IGBT and inductance), temperature, thermal warnings when temperature is too high, shut down automatically to stop refuelling.
All kinds of protection:
APF has all kinds of protection function: over voltage, under voltage, over current, short circuit protection, etc.

Join the design of the sys tem
Independent air duct:
Roach unique multilayer space heat dissipation design, can effectively isolate the environment dust adhesion, improve the product cooling efficiency, no additional consideration in the process of design for environment Element, system can adapt to different environment.
Modular design:
GROCH APF adopting modular design, small size light weight, installation without crane, forklift trucks and other large equipment, time and manpower. Wall design, installation Flexible, especially suitable for the place of the space is little.
Flexible stability:
25-100 A capacity of five modules, any capacity combination weaver, single tank capacity of up to 600 a, meet the demand of different capacity. Any module can realize all the work problems can, any module, the module will be able to run normally, in order to ensure the continuity of the safe operation of the system.

Harm of harmonic
Harm to the network
1. triggering control equipment, refusal or misoperation of relay protectiondevices and burn equipment or faulty tripping.
2. reduce the power factor, wasting energy.
3. reduce circuit breaker breaking capacity, increasing the circuit breakercapacity configurations.
4. cable losses, reducing the transmission capacity to accelerate the cableinsulation ageing and shortened cable life.

Damage to the equipment
1. local parallel resonant and resonant, seriously lowering supply security, resulting in frequent tripping and even damaged the capacitor Cabinet.
2. burned counters capacitance capacitors and protection components, busbar.
3. transformer copper and iron losses and stray losses, leading to lowerfever as well as the effective capacity of the transformer.
4. reduce load volume.
5. shorten the life of electrical equipment and precision instruments, or even damage the device.
