The protection functions of Phase Failure Phase Sequence Relay don’t be affected by current intensity of circuit or load, impulse current, imbalance current and load characteristic. The relay could long term work under full capability and full climate. Power consumption is lower than 2W.Phase failure protection, Phase loss protection, Voltage imbalance protection and Anti-lighting, anti-surge function.Can be directly inserted into your standard 35mm TH Road rail. One other occasions, you can fix the Phase Failure Phase Sequence Relay by M2-M4 screws(screws not included here).Please pay attention to the voltage before buying to make sure the buzzer can be used at your place.

i want points of differences ,atleast 4
And got the following answer:
Instrument transformers are used primarily where you are sampling a quantity such as voltage and you do not expect to have any load to speak of on the transformer. Some examples are: Voltage measurement of a substation bus where the nominal voltage is 7200 volts to ground and the current levels may reach 2000 amps. The power transformer supplying this type of load will have a voltage drop internal to it as will bus sections, etc. To ensure you are measuring the actual voltage at any particular point you would attach a potential transformer. This instrument type transformer would only be installed to measure voltage, no intentional load would be placed on the transformer so that the losses in the transformer are at a minimum. With a ratio of say 60 to 1 if you are reading 120 volts then you know the point at which is attached to the bus is at 7200 volts. If however you added load to the instrument transformer a voltage drop would occur in the transformer and you might read 115 volts on it's secondary side and now you would say the buss voltage is at 6900 volts, which would be incorrect. Instrument transformer are used for: 1) Potential measurement 2) Relay & Control 3) Phasing checks between sources 4) Synchronizing of sources (generators) 5) Metering Power transformers are what they are termed. They are built to transformer power from one voltage to another at high load levels. At a power plant these may be 300 MV more or less. At regional power substations they may be 50 MV to 300MV. (MVA - million volt-amps). At distribution substations they are usually smaller between 40 MV down to 2.5 MV. They are generally used for: 1) Stepping voltage up from say 13 kV to 500 kV at a power plant. 2) Placed in parallel operation to support more load 3) Wound such that they are attached as Delta-Delta, Wye-Wye, Delta-Wye, Wye-Delta, Zig-Zag, etc. to match phase relationships between sources 4) Large power transformers often has Load Tap Changes, meaning they may changing "Taps" by changing the turns ratio and thus adjust the output voltage to a preset level while carrying full load. 5) They may be used as grounding banks 6) They may be used as balancing banks In general they are subject to high load variation, voltage regulation, short circuits, lightning strikes, etc. and must be able to withstand all that and continue to work properly.

The phase loss relay operate particularly well with distinct applications that are precise to energy distribution and protection. The relays come with wide adjustment ranges using a scale that is easy to study either in three or four digits in accordance with the model. These phase loss relay aid in rising the flexibility with the applications, decrease the all round power and maintenance costs. You can find relays which are utilised for common purposes which come in trusted styles with fast replacement choices. And you’ll find models that are utilised for industrial applications and heavier duty applications that perform on large loads. These goods are produced to meet the lifetime industrial control desires of the applications.
Their most recent products will be the Time counter, Timer Delay, phase loss relay, Quick Connect Couplings, Electronic Motor Couplings, Aluminum Couplings, Morse Couplings and different other people. The web page presents a detailed description of each and every model in a variety of categories of phase loss relay couplings and sensors. These products are particularly helpful for high-risk applications. The phase loss relay are also offered with attributes like several timing ranges and functions. The corporation is presently on the lookout for agents and dealers who can promote and sell their factory created merchandise.
