The digital, solid-state CDP series is adjustable for Class 1 through Class 60.
The wide range of class adjustments with the Model CDP will allow the relay
to be adjusted for the maximum protection of the motor. Thus, if a motor is
normally up to running speed in six seconds then the overload relay may be
adjusted for Class 1 with a nominal trip time of 12 seconds at 125% overload.

Class px ct?
Class PX is the definition in IEC 60044-1 for the quasi-transient CT formerly covered by Class X of BS-3938, commonly used with unit protection schemes. These are Protection CTs used for Earth fault protection. Knee point voltage is an important parameter for these type of CTs. Shaikh
What is the power factor when the current and voltage are in phase?
The power factor of a load is the cosine of the angle by which the load current lags or leads the supply voltage. So if they are in phase (phase angle is zero), then the power factor must be unity (1).
What are the 4 parts of a cathode ray tube?
four parts of CRO: 1-crt 2-horizontal section 3-vertical section 4-power supply
How do you wire start and run capacitors into an electric motor?
Connect your start capacitor in series with the start winding.Connect the run capacitor in the common terminal and Line 1 of the power supply.
How do you reduce the Power dissipation?
Answer for mechanical systems:Use oil or grease to reduce friction!Answer for electrical systems:Making the voltage as high as possible is a good way to reduce power loss.ExplanationThe voltage drop along a conductor is proportional to the resistance and to the current carried. (V=IxR) So, for a given quantity of Power (W=VxI), if the voltage is made as high as possible there will be less current flowing and therefore less power loss.
