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.
Inner Diameter (select site cable and inner diameter of zero-sequence CT), See table1

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: Maintenance of electrical equipment, security measures to ensure that what
- 4, before each class must listen carefully to the previous report on the operation of the equipment, to understand the existing state of all equipment. 5, the maintenance of electric power equipment insulation must wear protective equipment, strict stop transmission system, stop transmission to a person responsible for the maintenance of switch control equipment, the switch to power and hang people work, no power "brand, and special care, strict implementation of the mine management regulations to stop electric. Only when the gas density is around 20 meters range is lower than 1%, only open power equipment, and use the same grade pencil test in cut off power supply, after the confirmation, discharge, and then can carry out comprehensive maintenance, maintenance end is correct, it can send electricity.
- Q: What is the installation equipment of the transformer on the power installation project
- It is composed of oil immersed transformer, low voltage outlet cabinet, lightning arrester, conductor, concrete pole, insulator, hardware and iron accessories, concrete prefabricated components. Construction method:
- Q: Power equipment sales process, the customer asked the most questions thank you
- The questions asked by customers vary from person to person:1, the brand or model in which the same industry used, that is, customer performance, the region has no performance;2, product quality, how to use life, and other domestic brands compared to what level, quality assurance, such as a few years;
- Q: What are the necessary equipment for power line project?
- There are connection tools, such as hydraulic pliers, crimping pliers, pressing tools, connecting tube, detonation pressure tube; the last is a measuring device, theodolite, rod, etc. in addition to the measuring rod; excavation tools such as shovels, iron, hammer and so on.
- Q: Part of the rated voltage of the power equipment is marked 10.5kv, and this is similar to the label 10KV power equipment what is the difference?Consulted a lot of teachers, but it is said that this is the old and new two methods, I would like to ask what is the basis of this, it is best to have a national standard for reference
- 3, rated voltage transformerRegulations, to accept the power of the primary winding, the output power of the two windings, the general, the primary winding voltage = network voltage, the voltage of the two winding due to the consideration of the loss, higher than the network voltage of 5% to 10%
- Q: The company has a number of power equipment to be exported, need to go through the sea, the technical requirements of three, I would like to ask what is the three here? How to check whether the complete sets of components used to do three treatment? Please exhibitions, grateful!
- As well as protection, control, measurement and other devices are assembled in a whole cabinet, there are a number of high-voltage switchgear in power plants, substations or power distribution equipment installed after the installation of the power plant is called a complete set of power distribution equipment.
- Q: Electric power equipment includes what steam turbines are used in what areas of what companies need steam turbines
- The main power equipment including power equipment and power supply equipment two categories, power generation equipment is the main power plant boiler, steam turbine, gas turbine, turbine, generator, transformer, power supply equipment is the main transmission line, voltage transformer, contactor etc..The steam turbine is the power equipment, except for the thermal power plant and central heating power station, is also used to drive other equipment, large fan and water pump, ship steel plant, such as large enterprises, pharmaceutical chemical screw compressor etc..Steam turbine and thermal power stations are generally used as the main steam turbine companies, followed by a wide range of applications in pharmaceutical, chemical, metallurgical, petrochemical enterprises.
- Q: Power test equipment sales to find power supply company which departments? Which departments of the power supply company will use the power test equipment?
- Procurement is generally the Department of materials management, to find a high class, livelihood, materials department
- Q: Withstand voltage test, power equipment insulation unqualified reasons?
- Test methods and voltage measurement methods are not correct. For example, when the transformer is tested, the non - Test winding is not connected to the ground, and the non - tested winding may be discharged to the ground. For example, the test of large capacity test, the voltage is still on the low side of the measurement, due to the capacitive effect, the actual increase in the voltage on the test sample over the test voltage, resulting in the breakdown of the subject matter, misjudgment is not qualified.
- Q: Rivers and lakes emergency, there is a 110kV and 10kV power supply line works, I would like to ask this kind of power project warranty items, scope, life and other detailed provisions where can be found? Are there relevant regulations? For example, if the provisions of the housing construction warranty, you can check the "construction quality management regulations," but the warranty content of power projects, what information should be checked? Note that the warranty is not repair. Waiting for good people reply, satisfaction and then points.
- Implementation of electric power projects in accordance with the general agreement between the two sides agreed to the implementation of the warranty period, equipment installation and renovation works.If the contract does not specify the warranty period, the electrical pipeline.
