Types of Arc Control Pots

Types of Arc Control Pots: There has been a continuous development in the types of arc control pots, the two basic forms of which are shown in Fig. (15.6). As…

Air Break Circuit Breaker

Air Break Circuit Breaker: The arc interruption process of Air Break Circuit Breaker is based on the natural deionization of gases by a cooling action. The arc is resilient and…

Characteristics of Rate of Rise of Restriking Voltage

Characteristics of Rate of Rise of Restriking Voltage: The important Characteristics of Rate of Rise of Restriking Voltage which affect the circuit breaker performance are: amplitude factor, rate of rise…

Static Distance Protection Relay

Static Distance Protection Relay: Static Distance Protection Relay are characterized by having two input quantities respectively proportional to the voltage and current at a particular point in the power system,…

Static Amplitude Comparator

Static Amplitude Comparator: If the two input signals are S1 and S2 the amplitude comparator gives positive (yes) output only if S2/S1 ≤ K (Fig. (11.1)), S1 is the operating quantity…

Transistor Use in Static Relay

Transistor Use in Static Relay: Transistor Use in Static Relay - In its simplest form, it consists of two pn junction diodes coupled together by a very thin common base,…

Transistor Relays

Transistor Relays: These are the most widely accepted type of static relays, so much so that when we say static relays, we can safely infer transistor relays only. The transistor…

Transductor Relay

Transductor Relay (Magnetic Amplifier Relay): Transductor Relay - Since relays now have to perform much more complicated functions, many types tend to become very complex mechanically, and hence costly, to…
