The first question that knocks our mind before starting on the working of a wattmeter is “what it is used for?”. As evident from the name, a wattmeter is used for measuring the total power across any circuit.

We know that the units of power are watts, so as for many other instruments, we can easily know that where the name of this instrument comes from. In simple words, a wattmeter is used for measuring the watts in the circuit.

Hi it’s Steven Mill. I think I’ve never written on this topic before, so let me tell you about motor starters…

starter device

A starter, more or less acts as a supervisor of the motor. It controls the power supply, defies switching of overloads, and also takes on the duty of disconnecting the motor from the mains, when deemed necessary.

As we can read about the topic:

“A starter can be defined as a combination electric motor controller, which can start or stop the motor with the help of external switches, protect the motors from getting overloaded, and disconnect them from the mains, in case of a serious power or load fluctuation, by taking help from the integral disconnecting devices.”

Next part of the “Measuring instruments” tutorial series. Enjoy!

So here we are with another measuring instrument. The one which I have chosen for today concludes all our measuring instruments in a much esteemed way. Yes, I am talking about the oscilloscope, which would be justified to explain now as we have already been through all of its components like voltmeter, ammeter, distortion meter etc.

Here’s a testimony that a professional from Boston, USA sent us two weeks ago. Eric S. wanted give you advices about static UPS, that’s why he wrote this article based on his experience.

You want to share you experience as well? You can send us a mail, we’ll be glad to publish it on the blog!

Introduction

static UPS for your data center 1

Taking a decision on the power requirements of a static UPS for your data center, can only be made after taking into consideration the various factors affecting it.

Owing to my experience in this field as a qualified UPS installation and maintenance expert, I can tell you that, one cannot choose the power size of a static UPS for a data center, solely depending on the power distribution scheme.

In fact, I strongly consider taking the following general and critical elements into consideration before you take a final decision:

New article from the series of tutorial that Nasir – one of our most prolific members – wrote on measuring instruments. This time he focuses on ohmmeter.

You too can send us articles. Just send a mail to the team!

What is an Ohmmeter?

Ohmmeter is another interesting measuring instrument that is used for measuring the resistance between any two points in the circuit. It is of extreme importance and is widely used in circuit analysis and debugging nowadays.

As we know that the units of resistance are ohms, so we know that where the name of this device comes from, as it measures the ohms between any two points in the circuit.
