Wedge-shaped pieces of metal with teeth or other gripping elements that are used to prevent pipe from slipping down into the hole or to hold pipe in place. Rotary slips fit around the drill pipe and wedge against the master bushing to support the pipe. Power slips are pneumatically or hydraulically actuated devices that allow the crew to dispense with the manual handling of slips when making a connection. Packers and other down hole equipment are secured in position by slips that engage the pipe by action directed at the surface.†

The large wrenches used for turning when making up or breaking out drill pipe, casing, tubing, or other pipe; variously called casing tongs, rotary tongs, and so forth according to the specific use. Power tongs are pneumatically or hydraulically operated tools that spin the pipe up and, in some instances, apply the final makeup torque.†

Clamp Meter (Tong Tester) is one of the most useful test equipment. This post will discuss Tong Tester types, Operating Principle and how to operate it.

Clamp meter is often known as Tong Tester also. It is an easy to use test equipment and is useful in the measurement of a live-conductor without damaging / powering down the circuit. One of the biggest advantage of this equipment is that one may take the measurement of a high value current even without powering off/shutting down the circuitry under test.

A current transformer based Tong Tester (Clamp meter) consists of two clamps made of Ferrite Iron. These clamps are independently wrapped up with Copper coils. Together both of them forms a magnetic core which actually does the measurements. The Electro-magnetic principle says that “whenever a current flows through a conducting material, it causes the generation of magnetic-flux”.

Now, let us assume that the conducting material from which the current is passing through is the primary arm of the transformer. Due to the current’s movement, a magnetic field is generated in it. When the arm of tong tester is placed for measurement, it acts as a secondary winding of the transformer. The iron core of the arm of tong tester concentrates the magnetic field of the primary winding (i.e. conductor) and hence a current in proportion to the primary-current is generated by electromagnetic-induction. This arm of the tong tester is connected to a measurement circuitry which in turn provides the current-reading finally.

The Hall Effect Clamp meter can also measure DC current as the core is capable of concentrating DC magnetic fields also. However, When measuring the current, these clamp meters must be zeroed to avoid presence of errors due to magnetic field of Earth or any other magnetic field source in near vicinity.
