Yes. Transformers are designed to work with AC.
see http://ezinearticles.com/?Testing-a-Transformer--How-To-Accurately-Test-A-Transformer&id=56803 Normally to test a CT we go on with two tests 1. the primary injection test 2. the polarity test 1. primary injection test: a particular amount of current is made to flow through the primary and the amount of current we get from secondary is measured. 2. the name itself describes the test...
Pat testing equipment allows you to test your electrical equipment to make sure that it is safe to use. It stands for Portable appliance testing which basically means it allows you to test portable appliances.
Discuss the assessments that must be made prior to testing controls

testing polarity of CT by Flick test . A centre zero voltmeter is connected across CT secondary .A 1.5V battery is touched to primary of CT .the deflecting of pointer should be similar in case of each CT to be connected in same protection .
You will be able to find out the polarities of the windings. You can just put a digital meter on one winding and then touch the battery to the other side to see which polarity it has.
A battery analyzer is an electronic gadget proposed for testing the condition of an electric battery, going from a straightforward gadget for testing the charge really display in the cells and/or its voltage yield, to a more far reaching testing of the battery's condition, in particular its ability for gathering charge and any conceivable defects influencing the battery's execution and security.
There are a great many. but to keep it simple: (a) pressure-testing the cables/switchgear/transformers/etc. (i.e. testing the insulation using high-voltage test sets); (b) testing the operation of the switchgear; (c) testing the operation of the protective relays. ...but lots more.
This procedure, however, cannot detect biochemical or chromosomal alterations in the fetus.
Start with checking/testing condition of battery and battery connections.

The term "13" battery testing is a term used to describe the type of testing that computers and other electronics go through. It is the type of testing that is used to show that it works efficiently.
try testing the battery
Depending on the equipment required for the substation,some of the tests are as follows: meggering,hi-pot testing,continuity checks,c.t. testing,relay testing,ngr testing, capacitance bridge test's on transformers.
Yes. I recommend testing the battery or take it to auto zone they will check for free.
