forest fire: secondary succession Students | Britannica ...
Secondary succession takes place following a major disturbance, such as a fire or flood. Farmland that has been abandoned also can undergo secondary succession. The stages of secondary succession are similar to those of primary succession with one important difference: primary succession always begins on a barren surface, while secondary succession begins in an area that already has soil.

Secondary Oil Recovery This method involves the injection of gas or water, which will displace the oil, force it to move from its resting place and bring it to the surface. This is typically successful in targeting an additional 30% of the oil's reserves, though the figure could be more or less depending on the oil and of the rock surrounding it.

For example, if the primary current enters the positive terminal of the primary, power is delivered to the primary. Thus, the secondary must be supplying power which means that the secondary current must exit the positive terminal of the secondary,, the secondary current is opposite the phase of the primary.

Primary Injection Testing Solutions SMC
Primary injection testing is essential in commissioning and verifying a protection scheme since the secondary injection test does not check all the components in the system and the condition of the overall protection installation; unlike the primary injection testing, the secondary injection tests do not simulate the real operating conditions, it would not reveal a defective CT, whether that CT is the correct ratio or .

Using SinglePhase Transformers to Create 3Phase Systems
The secondary voltage is 208 wye/120V, 3phase, 4wire. Note that the neutrals of the primary system and the transformer bank are tied together. As such, part of the load current will flow on the primary neutral should the 3phase load be unbalanced. That's why it's very important the neutrals be tied together as shown.

The primary winding and the secondary winding are separate and not connected. An . autotransformer . has its windings interconnected so that the primary and the secondary share the same windings. Autotransformers, therefore, have an electrically con nected primary and secondary. These two basic types of transformers are shown in Figure 1410.
