Relay Test Block

Item Code: NW-RTB-BC

Relay Test Blocks Facilitates easy in-situ, onload testing of relays, metering and control panels without disrupting load circuit.The housing is robust, high grade phenolic mouldingThe terminals are brass, duly nickle plated. The contacts are spring loaded, silver plated and supported by phosphor bronze strips. Each contact is separated with a SRBP shroud.Screws are provided at the rear for terminations. Alternatively, studs with nuts and washers could also be provided.
Sealing holes on cover studs are provided to prevent unauthorized access. The front cover can be removed for test purpose and replaced, thereafter. This cover is fitted with a silver plated contact finger to close the trip contact, when inserted. Otherwise, the trip contact would remain open. Thus the contact finger on the cover, completes the entire circuit. Isolation of the trip circuit is feasible by removing the contact finger fitted to cover thus avoiding unwarranted tripping under test conditions.

 Specifications:

• Insulation: conforms to IS-3231
• Tested for 2.5 KV Resistance value: 100 Mega ohms

Relay panel accessories (relay test blocks)(interface test system)
Relay test plug. Series NWRTP-01
This is a multi finger Test Plug when inserted, open circuits the contacts in the Test Block. The Test Plug consists of 28 nos. 4 mm. dia. sockets. Each socket corresponds to the numbered case terminal and is identified by identical
number.

NWRTP-01 Test Plug when inserted into the Test Block it is securely retained by means of 2 nos. knuurled knobs. Shorting wire links are also provided with the NWRTP - 01 test block. The following accessories are provided with each NWRTP-01 Test Plug.:

4 Nos. 150 mm long cable consisting of 4 mm plugs at both ends,
4 Nos. 50 mm long cable consisting of 4 mm Plugs at both ends.
6 Nos. 4 mm plugs which accepts flexible insulated cable upto 2.5 mm2 tor test lead purposes.
Important
Before inserting the Test Plug NWRTP- 01 into the Test Block NWRTS- 01 it is essential that sockets in NWRTP-01 that  corresponds to the current transformer secondary windings are shorted using external shorting wire links. This is to  avoid dangerously high voltages. It is also essential to ensure that the ammeter is on the correct range and that it is  connected to its test leads, before inserting a test plug to measure current.

Test Plug. Series NWRTP-02

This is a single finger Test Plug that can be inserted into individual test positions as shown in figure # 1. NWRTP-02 consists of two contacts which are insulated from one another. Each contact is connected to a lead wire. For polarity identification, one core is red and the other black. Each NWRTP-02 Test Plug is provided with 1.0 mm2-twln flexible cable of 1.5 metre length.

Important

• It is essential that adequate precautions and safety measures are taken before proceeding with the measurements and testing.
•  When using for voltage measurements, it is possible to access hazardous live voltages via the single finger Test Plug.
•  While monitoring secondary CT current, the leads from the single finger Test Block must never be open Circuited. If done, it can   generate lethal level voltages.
