Zero Sequence Current Transformer
Product Overview
When circuit grounds, CT could senses zero-sequence grounding current. To be equiped with relay protector or signal devices, it help device components act for the purpose of protecting or monitoring circuit.
MRD-L series zero-sequence CT is a kind of cable type, using ABS engineering plastics as casing, poured by resin. With beautiful appearance, good hermeticness, high insulation, high sensitivitym, good linearity, easy installation and wide application, it is not only suitable to magnetic relay, but also to electronics and mico-computer devices. CT type is determined by the operation way of user.(Neutral ground, unground,ground by high-resistance,low resistance or arc suprression coil.)
MRD-L series zero-sequence CT core is made of ZH120-130 cold rolled silicon steel sheet imported from Japan with advantages of smooth surface, constant thickness, good conductivity, strong sensitivity to magnetizing, accuracy and stability.

Character
1. Maximum capacity, better limite voltage effect, more widely applicable scope, stronger tolerance , long lifespan
2. Voltage impact coefficient is 1, under the various kinds of electric voltage waveform, the voltage values are equal
3. With zinc oxide nonlinear resistors and discharge gap between the structure, make the two are complementary protected. The spark gap make the State-of-Charge of zinc oxide resistance to zero, Zinc oxide resistance nonlinear characteristics also make the spark gap action without free-wheeling in future, The spark gap no longer bear arcing tasks, and improve the service life of the product;
4. Four lines connect method, can be greatly reduce the voltage of phase, the reliability of the protection is greatly improved;
5. Valve plates and the spark gap assemble space, and mutual influence, discharge electrode is not easy to damp, be oxidated, make action value more stable and reliable.
6.Take overvoltage action techniques and fault automatically function , realize the device maintenance free, at the same time, to avoid the tedious work periodically, to solve the engineering and technical personnel to worry about the problems of the equipment safe running .

- Q: The insulation level of the electrical equipment in the neutral grounding system shall be consideredA. phase voltage;The square root of 2 phase voltage B.;The square root of 3 phase voltage C..Great God in the end this election? I am very tangled!
- For example, 220kV transformer (YNYnd11) insulation level high voltage side is LI950AC395-LI400AC200, the front half part (head) of the lightning impulse voltage and power frequency withstand voltage were significantly higher than that of the second part (neutral side). According to the power frequency withstand voltage needs to achieve 1.6 times the rated voltage requirements, the first end of the line voltage is considered in accordance with 220kV, the neutral point according to the phase voltage (127kV) considerations. But there are some places are fully insulated, that is, according to the line voltage calculation.The triangle connection must be considered by the line voltage. Overall, C is definitely right.
- Q: What is the definition of abnormal equipment, equipment failure, equipment failure and equipment accident? From which power standard?
- Exception: may be a precursor to the accident, has not yet caused the loss, the cause is unknown,Such as the normal operation of the cable overheating, burning plastic taste
- Q: What is the LCP cabinet of electric power equipment
- Local control cabinetLocal control cabinet installed in the work site, which is likely to have PLC, the scope of the control cabinet than PLC wide
- Q: Power equipment sales process, the customer asked the most questions thank you
- 6, some of the common causes of the failure of the equipment and processing needs to understand, it is possible that users will ask some of the problems they encounter oh;The last thing is the most important, in order to get the order: it depends on how to ensure that the interests of their clients, and this look at your company policy, the interests of the customer relationship and ensure equal importance! Basically so many questions, other topics. Absolute hand!
- Q: What is the specific name of the double name of the equipment in the electric work sheet? Know please enlighten me.It would be better if you had a sample ticket.
- The double name of equipment refers to the name and number of the equipment.The name of the equipment is Chinese, the number is Arabia. Together is a double name. The same station, will not appear the same name, or the same number, is the only. The only combination of the two can be more accurate.
- Q: What specific enterprises and units are used to test the power of the equipment ah
- The other really did not ~ ~ ~ ~ ~What do you mean by electrical testing equipment??? High? Low?
- Q: Is there a warranty period for power equipment?
- Now there is no, you can view the relevant national standards for electrical equipment standards, as well as high and low voltage equipment test manual. Online search, easy to get.
- Q: Hello, I would like to ask what are the main rotating equipment in the power system? What is a rotating device?
- The transformer is non rotating equipment. There are a lot of rotating equipment in power plants, such as fans, fans and so on, of course, the most important is the generator
- Q: The two devices of the power system have those
- Internal equipment:1, measuring meter, such as voltmeter, ammeter, power meter, electric energy meter for measuring electrical parameters in the circuit.2, insulation monitoring device.3, control and signal device.
- Q: What are the two devices in the power system
- . Such as measuring instruments, relays, switches, buttons, automatic control equipment, computers, signal equipment, control cables and some power supply devices, etc..
