FUNCTION | Neutral Grounding Resistors are used to protect power transformers, power generators and other associated equipment in your power systems against 50/60 Hz faults (short circuit) and transient phenomena (lightning). |
SPECIFICATIONS | There are six parameters needed to specify the neutral grounding resistor. 2. Rated fault current. 3. Rated “duration time” of the line to neutral voltage not exceeding the allowable temperature rise. 4. Rated Resistance. 5. Application environment, indoor or outdoor. 6. Enclosure material, ss plate or normal cold rolled sheet. |
RANGE | • Rated current: from 1 amp to 2000 A • Rated voltage: from 0.4 to 35kV • Rated Resistance: from 1 ohm to 2000 ohm • Rated time: 1 sec to continuous time rating |
TESTING AND QUALITY | All Mingrui Neutral Grounding Resistors are designed, rated, manufactured and tested in strict compliance with IEEE-32. Routine tests performed on each Neutral Grounding Resistor are measurement of resistance, high voltage power frequency, insulation measurement, aspect verification, dimensional control. Mingrui’s internal quality system has been developed and certified under ISO 9001 quality system |
CONSTRUCTION | Standard unit includes the stainless steel resistor assembly plus all the required insulators, internal connections and hardware installed in a standard safety enclosure. Neutral Grounding Resistor units are completely assembled, prewired, and tested at our facility. For shipping all units are crated for added protection and ease of handling. |
ENCLOSURE FEATURES | • Forged eyebolts in all four corners for easy hoisting. • Corrosion resistant nameplate provides complete ratings and manufacturers information. •Heavy gauged enclosure polyester powder coated finish provides maximum protection. |
ENCLOSURE OPTIONS | •Stainless steel, cold rolled plate construction. Custom paint finish is available. |
OPTIONS | • Current or potential transformers mounted and prewired at our facility |
- 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 is the good rate of equipment determined by the rating of substation equipment
- The "system" can easily calculate the depreciation and repair costs of fixed assets in order to determine the economic life of the equipment, the best time to update. As a result of the "system" many functions of the set, so that enterprises can accurately grasp the technical status of the equipment, so as to determine the technical life of the equipment is very useful.
- Q:I would like to open a company on the construction of power equipment, what needs to be prepared? (including qualification level, capital requirements, etc.) the more detailed the better
- In addition to the requirements of industrial and commercial registration, there are two industry qualification requirements. Both are the higher the level, the higher the level of examination and approval department, the highest level, respectively, need to be approved by the State Ministry of housing and national home appliances. The newly established enterprises with no performance can only start from the lowest level four.
- 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!
- The complete set of power distribution equipment is a complete set of equipment supplied by the manufacturer. The electric main circuit is divided into a plurality of units, each unit is a circuit, and the circuit breaker, the knife gate, the current transformer and the voltage transformer of each unit are connected
- 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:What is the redundancy of electrical equipment
- Redundancy is a part of the system that is repeatedly configured. When the system is in trouble, the redundant components are involved in the work of the faulty components, thereby reducing the failure time of the system.
- Q:How to strengthen the management of electric power information communication equipment
- As an important infrastructure in the process of automation and management modernization of China's power grid dispatching, the high efficiency and scientific performance of power information communication equipment can effectively promote the safe operation of power grid.
- Q:Withstand voltage test, power equipment insulation unqualified reasons?
- Without proper consideration of the atmospheric conditions that affect the insulation characteristics. Because of the pressure, temperature and humidity have a certain impact on the spark discharge voltage and breakdown voltage, without considering these factors may lead to equipment failure.
- Q:What are the customer groups faced by power intelligent equipment?Products such as electric capacitor reactive power control (capacitor module), reactive power compensation controller, the series of electric power meter, active filtering equipment, power monitoring system, energy management system, operating system and DC power system accessory products.
- Power capacitor is a kind of reactive power compensation device. Power system load and power supply equipment such as motors, transformers, transformers, etc., in addition to the consumption of active power, but also to absorb reactive power. If the reactive power is supplied by the generator, it will affect its active power output, not only uneconomical, but also lead to poor quality of the voltage, affecting the user's use.
- Q:Hello, I would like to ask what are the main rotating equipment in the power system? What is a rotating device?
- Generators, motors, blowers, air conditioning, transportation, lifting, etc.. Rotating machinery can be called rotating equipment
