1,Brief Introduction to Product
MRD-FD type neutral ground resistor cabinet is complete equipment specially used by generators in power plant which adopts high-resistance grounding for neutral. The voltage grade for generator mainly ranges from 6kv to 20kv. When one point of the stator grounds, the device is able to limit the grounding current at a reasonable value, and effectively restraint arc flash transient overvoltage associated with single-phase grounding.

2.1 Parameters of Grounding Transformer
Insulation class：H
Cooling：AN
Protection Level: for paper-insulated dry type grounding transformer, the PI is divided into IP00 (no enclosure), IP20, and IP23 (with enclosure) .
Insulation level, impedance voltage on-load loss and no-load loss are according to relevant national standards.
Insulation resistance testing: high voltage-low voltage and to earth≥300MΩ，and low voltage-earth≥100MΩ.
- Q: What are the characteristics of the grounding of the power system and equipment?
- The grounding - is the need for work and set up the ground, such as: high current transformer neutral point grounding, primary voltage transformer neutral grounding, 380/220V three-phase four wire neutral grounding, etc..
- Q: In what way is it confirmed that the destroyer is an electrical device? Identification or what.
- The behavior of the power line that has been installed and has not yet been powered off shall be treated differently. If the stolen cut is not formally delivered to the power sector to use the line, should be handled in accordance with the theft case. If the actor knows the line has been delivered to the use of the power sector and steal cut wires, shall be designated as the crime of destruction of power equipment.
- Q: Power transformers and other equipment are what units procurement bidding, all those procedures!
- Power Grid Corp on the volume of business is greater, because their main business is to invest in the construction of power grids.There are also a small number of individual units, such as large projects and large enterprises.
- Q: Reactive power compensation methods commonly used in power equipment
- The centralized compensation is to set up the reactive power compensation device in the power distribution room to compensate the reactive power in the region. Due to the introduction of several kinds of compensation sampling is set at the point of measurement, so you can minimize the interest rate generated electricity.In the professional field and transmission line compensation (high and low), furnace low-pressure grid compensation, flameproof compensation device etc..
- Q: What are the effects of frequency variation on power users and power systems?
- Influence of frequency variation on power users and power systems:There is a close relationship between the frequency of power equipment and the operation of power system
- 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: How to run a company that operates electric equipment
- Look for people who want to use the electrical equipment, such as the operator of the power station,
- Q: Is there a warranty period for power equipment?
- Warranty period is not specified, is determined by the relevant test standards
- Q: Definition of power equipment defects
- General defectIn the short term will not be reduced to major defects, emergency defects, although the impact of the operation but can still operate.
- Q: The state of power system equipment is divided into four states
- (4) maintenance status. Circuit breaker and isolating switch device in the open position, the circuit breaker can be divided, and the control switch, fuse (or switch) switch maintenance should be off line and on both sides of the grounding switch (or installed ground), and hung signs work.
